Take a tour of San Cristobal Cathedral in Havana, Cuba – part of the World’s Greatest Attractions travel video series by GeoBeats. For a taste of Cuba's rich history, visit Havana's Cathedral Square. San Cristobal Cathedral was built in the mid 18th century. This Baroque masterpiece once housed the remains of Christopher Columbus. It has been famously described as "Music Set in Stone." The structure is unique in that one tower is wider than the other. San Cristobal, made partly of coral, glows in the Havana twilight.
