After Castro: A snapshot from Cuba

At the Paseo del Prado, beside the central square, hotels line the streets. El Capitolio, the seat of the government until the Cuban Revolution in 1959, has now become a place for social gatherings, where Cubans meet each other to exchange gossip and play games.

"The Cuban government made my dream to be a nurse and help people a reality," said Mirta Gomez, a retired nurse. Before the revolution, educational opportunities in Cuba were reserved for the elite. Once Castro came into power, Gomez was able to study nursing. She spent most of her career at Havana's Central Hospital. She still helps out and trains new nurses. Her new hobby is selling flowers.

Across Havana, buildings are being renovated to make way for the return of American tourism. As the government authorizes certain private business, hotels and restaurants are leading the construction boom. This building will be a group of "casas particulieres," similar to a bed and breakfast, in the Vedado neighborhood. Cubans need to apply for a license to rent rooms in their homes to foreigners.

Francisco Arrosa, 75, reads Granma, the Communist Party newspaper, as he waits for new clients. "We are socialists. What Fidel and the Revolution started, the Cuban people will keep," the car mechanic said. "We may not be wealthy, but every Cuban has access to food, education, healthcare, and housing. These things are the revolution."

Tourists take photos from an old American car driving through Plaza Central. With the decades-long US embargo, vehicles from the 1950s and 1960s were the only option for Cubans for many years. Now, Korean, Chinese, and some European brands are entering the island's market. The old cars continue to be used as taxis or for tourism.

Along one of Havana's most popular boardwalks, Cubans can check their e-mail or read government-approved websites. In 2015, the Cuban government opened the first public wi-fi hotspots in 35 public locations. However, the internet is one of the most censored in the world and essentially unavailable in private homes.

Canadians make up the largest percentage of Cuba's tourists, but with the resumption of flights and cruise ships from the US, the number of US visitors is expected to surge this year.

As an island nation, fishing plays an important role in Cuban culture, including in its cuisine. Generation after generation have made their livelihood on the practice and fish is one of Cuba's biggest exports. US tourism companies already have their eyes on the country's pristine coastal waters.
