There will be no Fidel Castro streets or plazas in Cuba, in keeping with the late revolutionary leader's wishes, as spelled out in a law Cuban legislators passed on Tuesday.
President Raul Castro, 85, said that before dying at the age of 90 on November 25, his brother Fidel had requested that no monuments or statues be erected in his honor, and that no streets or buildings be named after him.
Lawmakers adopted the bill implementing his wish unanimously on Tuesday.
While he was an omnipresent figure in the lives of Cubans after taking power in 1959, Fidel Castro always opposed the erection of statues in his likeness. No streets or buildings are named after him in the Communist-led Caribbean country.
He also decreed that his name and image not be used for commercial or advertising purposes.
However, he did make an exception that would allow artists to use his name, people to cite it at political rallies and workplaces, and for a research institute on his role in history to bear his name.
Official media reports did not immediately make clear what penalties those breaking the law would face.

Cuban President Raul Castro and US President Barack Obama sparred over human rights issues including the American prison at Guantanamo Bay and Cuba's political prisoners.
At a historic news conference, Mr Castro said if he was given a list of political prisoners, he would "release them tonight".
The White House has said it has given Cuba lists of dissidents in the past.
Mr Castro does not view the prisoners as dissidents, US officials said.
That disagreement is central to the conflict between US and Cuban officials.
More needs to be done to lift the US embargo on trade with Cuba, Mr Castro said, adding that the Guantanamo Bay detention camp must close.
Mr Obama, the first serving US president to visit Cuba since 1959, said the trade embargo would be fully lifted.
"Cuba's destiny will not be decided by the United States or any other nation... The future of Cuba will be decided by Cubans not by anybody else," Mr Obama said.

The Failde Youth Band entertained the guests, who dined on shrimp mousse, cream soup flavoured with rum, and traditional pork with rice and plantain chips. Waiters passed round Cuban cigars after dinner.
Earlier on Monday, Mr Castro defended Cuba's record on human rights and pointed to problems in the US.
"We defend human rights, in our view civil, political, economic, social and cultural rights are indivisible, inter-dependent and universal," Mr Castro said.
Media captionMember of the Cuban opposition, Clarisa Perez: ''We are living through extreme repression here''Mr Castro is not usually subject to any aggressive questioning from reporters and called the prisoners question "not polite", later ending the news conference by saying "I think this is enough".
"Actually we find it inconceivable that a government does not defend and ensure the right to healthcare, education, social security, food provision and development," he said.
Speaking to ABC News after the conference with Mr Castro, Mr Obama did not directly say he would be giving Mr Castro a list of political prisoners.
"We have given them a lists in the past and they have responded intermittently to our engagement," he said. "And this I think is an example of why it was my belief that this would be a more successful mechanism for us to advance the values that we care about than an embargo and silence and no communications."
Media caption'A historic occasion' in CubaPresident Obama and his aides hoped that the Cuban President, Raul Castro, would approach the news conference with an open mind.
The White House officials also hoped that Mr Castro would be receptive to new ideas and to new ways of doing things. Specifically, the US officials hoped that he'd take questions from reporters. Surprisingly enough, he did, marking a departure from his past.
The two men joked around during the question-and-answer period, and they worked out some of their differences. When one of Mr Castro's aides interrupted his boss during the conference, for example, Mr Obama looked annoyed. But he and Mr Castro moved on, talking about the future of Cuba.
In a similar way, Mr Obama and his aides hope they can overcome other issues, including difficult ones such as human rights, as they forge a new relationship between the two countries.
Mr Obama could not say exactly when the trade embargo would be lifted, but recognised it was necessary.
"The reason is what we did for 50 years did not serve our interests or the interests of the Cuban people," he said.
His administration has done what it can on lifting trade restrictions, he said, but further action will require Congress which is "not as productive in an election year".
He also said further easing of the trade embargo will depend on actions Cuba takes on human rights.

Mr Obama said it is not just Cuba that the US has "deep disagreements" about human rights with - it also has disagreements with China and Vietnam.
"I believe if I engage frankly, clearly, stating our beliefs but I can't force change on any country - it ultimately has to come from within - that is a more useful strategy," he said. "I have faith in people".
Reporters described the press conference as "tense" and "remarkable".
Karla Olivares, an independent journalist from Cuba, told the BBC's Tara McKelvey Mr Castro "talked more than usual" and the claim that Cuba does not have any political prisoners "complicated".
Before the speech, it was announced that Google was opening an online technology centre for free Internet access at much higher speeds than what is available on the island now.
Google hopes the centre will be part of a larger effort to improve Internet access in Cuba.

President Barack Obama is in Cuba for a historic three-day visit to the island and talks with its communist leader.
He is the first sitting US president to visit since the 1959 revolution, which heralded decades of hostility between the two countries. Mr Obama said change would happen in Cuba and that Cuban President Raul Castro understood that.
The two leaders are meeting to talk about trade and are scheduled to hold a joint news conference. Latest updates of Obama's visit
Media captionPresident Obama's visit is the high point of a recent easing of ties, which included the opening of embassies last year.For decades, the US and Cuba were engaged in a bitter stand-off, triggered by the overthrow of US-backed Cuban dictator Fulgencio Batista by Communist leader Fidel Castro in 1959.
The US broke off diplomatic relations and imposed a trade embargo.
But President Obama undertook two years of secret talks which led to the announcement in December 2014 that the two countries would restore diplomatic relations.
Since then, there have been a series of symbolic moments, such as the first formal meeting of Presidents Obama and Castro at a regional summit in Panama and the opening of embassies in Havana and Washington DC.
What have been the highlights of the visit so far?
Presidents Obama and Castro shook hands at the Palace of the Revolution in Havana ahead of their bilateral meeting on Monday.
They seemed visibly more relaxed than at their first official meeting at a regional summit in Panama just under a year ago and smiled broadly.

Image copyrightReutersImage caption The Obama family braved the rain in Old Havana But it was the visit to Havana's old town which brought home the long way US-Cuban relations have come since the thaw was announced 15 months ago.
While the plan to interact with Cubans in the streets was disrupted by a tropical storm, the image of the US president and his family braving the rain demonstrated to many Cubans his commitment to the new, warmer relationship.
What else is in store?
President Obama is due to get down to the nitty gritty of politics in a face-to-face meeting with Cuban leader Raul Castro.
Their meeting at the Palace of the Revolution will be closely scrutinised for signs of how much practical progress has been made.
Ahead of the meeting, President Obama said he believed that "change is going to happen here and I think that Raul Castro understands that".
He also told US broadcaster ABC that he would be announcing that Google had made a deal with the Cuban authorities to expand Cuba's poor wi-fi and broadband access. Internet access still restricted in Cuba
There have been a series of other agreements between the two countries since the thaw was announced, including commercial deals on telecoms and a scheduled airline service, increased co-operation on law enforcement and environmental protection.
Many Cubans are hoping their economy will receive a further boost from further openness and reforms as well as US investment. Cuban officials are banking on a growth in US tourists visiting the island as restrictions on US citizens travelling there are eased further.
On Sunday, US hotel company Starwood announced it had become the first US firm to agree a deal with the Cuban authorities since the revolution of 1959.
The company said it would be making a "multimillion-dollar investment" to bring three Cuban hotels "up to our standards".
What could possibly go wrong?
While President Obama's agenda was carefully discussed with Cuban officials, one thing the White House has insisted on is a meeting between the president and Cuban dissidents, whether the Cubans like it or not.
Among them are expected to be members of the Ladies in White, a group which campaigns for the release of political prisoners.
Media captionWho are the Ladies in White?Only hours before Mr Obama touched down, dozens of their members were arrested during their weekly protest in Havana.
The meeting between the dissidents and Mr Obama is scheduled for Tuesday.
Another main sticking point between the two countries is the 54-year-old US trade embargo.
While strolling through Havana's old town on Sunday, one Cuban shouted: "Down with the embargo!"
The problem for Mr Obama is that it can only be lifted by the US Congress, which is controlled by Republicans who have expressed their opposition to its removal.
On the Cuban side, analysts say there are conflicting sentiments within the Communist Party over hosting Mr Obama.
The Director General of the US division at the Cuban Foreign Ministry told the BBC's Will Grant that "matters of sovereignty of the Cuban people" would remain firmly off the agenda.
Media captionJosefina Vidal: "Matters that are internal decisions and sovereignty of the Cuban people will not be negotiated with the United States"Many observers have also noted that Mr Obama is not scheduled to meet Raul Castro's older brother, the leader of the Cuban revolution, Fidel Castro.
The elder Castro has only made one official statement about the thaw in relations, and it was hardly a ringing endorsement: "I don't trust in the United States' policy, nor have I exchanged a word with them".
President Obama will make history on Sunday when he flies to Cuba to visit the island and hold talks with its Communist leader.
The two-day visit will be the first by a sitting US president since Calvin Coolidge came 88 years ago.
Mr Obama will meet President Raul Castro - but not retired revolutionary leader Fidel Castro - and the pair will discuss trade and political reform.

It is hard to overstate the significance of this trip because as recently as 18 months ago, the idea of a US president stepping foot on Cuban soil would have been unthinkable, the BBC's North America editor Jon Sopel says.

Mr Obama and Raul Castro will sit together at a state dinner, there will be a joint news conference and they will discuss trade.
The White House has made it clear President Obama will meet political dissidents, whether the Cuban authorities like it or not. That is expected to include members of the Ladies in White group, wives of political prisoners.
This visit does not mark a complete normalisation in relations, however.
The 54-year-old US economic embargo of Cuba is still in place and can only be lifted by a vote in Congress. Meanwhile, Cuba still complains about the occupation of the US naval base at Guantanamo Bay.
Nevertheless enormous strides have already been taken, our correspondent says.
Mr Obama and Mr Castro agreed in December 2014 to end decades of frozen relations that began when Cuba's revolution overthrew a pro-US government in 1959.
Since 2014 there have been commercial deals on telecoms and a scheduled airline service, increased co-operation on law enforcement and environmental protection.
On Wednesday Mr Obama sent a letter on the first direct mail flight from the US to Cuba since the revolution.
And on Sunday, US hotel company Starwood become the first American firm to agree a deal with the Cuban authorities since 1959.
The US president is not scheduled to meet the man who led the revolution - Fidel Castro - but Cubans were reminded of their historic leader on Sunday as newspapers published pictures of him meeting Venezuela's Nicolas Maduro.
Analysts suggested the release of the pictures underlines conflicting sentiments within the Communist party over hosting Mr Obama. Image copyrightReutersImage caption Cubans were reminded of their "historic leader" as newspapers published pictures of Fidel Castro meeting Venezuela's Nicolas Maduro
Thaw in US-Cuba relations:
US-Cuba relations were frozen since the early 1960s, when the US broke off diplomatic relations and imposed a trade embargo after Cuba's revolution led to communism.
The embargo was estimated to cost the US economy $1.2bn a year.
US President Barack Obama announced moves to normalise diplomatic and economic ties in December 2014.
It followed more than a year of secret talks in Canada and at the Vatican, directly involving Pope Francis.
The plans included reviewing the designation of Cuba as a state sponsor of terrorism, easing a travel ban for US citizens, easing financial restrictions, increasing telecommunications links as well as efforts to lift the trade embargo.
The US reopened its embassy in Havana in August 2015, a month after Cuba reopened its embassy in Washington.
