Cathedral de San Cristobal - Old Havana
One of eleven Roman Catholic cathedrals on the island of Cuba. It is located in the Plaza de la Cathedral in the center of Old Havana. The church is thirty-four by thirty-five meters in size. This striking example of Cuban Baroque architecture was completed in 1777 by the Franciscans, after the Jesuits began building it 29 years earlier. Two large bell towers flank the façade, which is adorned with inlaid columns. It is said that the relics of Christopher Columbus were housed here from 1796 to 1898, however this has never been proven
Similar to the Capitol building in Washington, DC, but actually modeled on the Panthéon in Paris, the building was started in 1926 and took 5000 workers three years, two months and 20 days to construct at a cost of US$17 million. Recently restored (2018) and will now house the Cuban National Assembly. Set in the floor directly below the dome is a copy of a 24-carat diamond. Highway distances between Havana and all sites in Cuba are calculated from this point.
