Across the island, houses, restaurants, supermarkets, hotels and state-run stores have put up Christmas decorations, embracing a holiday eliminated by Fidel Castro soon after he came to power in the Cuban Revolution in 1959 and declared Cuba an atheist state.
"El Comandante" restored Christmas in 1998 after a landmark visit by pope John Paul II.
After an initially hesitant revival, the Christmas spirit is once again booming on the island.
"Christmas was a very deep-rooted tradition in Cuba. It was interrupted for 38 years, which is no small thing, and yet it made a comeback," said the secretary of Cuba's Conference of Bishops, Jose Felix Perez.

On the streets of the capital, the dashboards of cars are decked out with Santas, wreaths and mini Christmas trees.
Less playful decorations adorn the gates and courtyards of foreign embassies and the US interests section, set to regain its status as an embassy under last week's watershed announcement by Obama and Cuban President Raul Castro, who took over from his big brother Fidel in 2006.
This year, Perez said, "everything the two presidents announced is giving people hope that their lives will get better and there will be greater understanding."
In this country where Catholicism has long co-existed with local traditions that draw on both Christianity and African religions, state-run stores are brimming with Christmas gift baskets and restaurants and hotels are offering sumptuous Christmas dinners.
