Situated at the Plaza de la Catedral (the Cathedral Square) in the center of Old Havana, Cuba, the Havana Cathedral is one of just 11 Roman Catholic cathedrals found in Cuba. Completed in 1777, it is considered one of the most important and finest examples of the Baroque architectural style in the country. The cathedral is made out of coral that was cut off reefs on the bottom of the sea and if you take a closer look at the walls, you can actually find fossilized marine animals there.
