The Cathedral of Havana is an iconic work of what is known as Cuban Baroque and the most remarkable of our colonial churches. The glorious baroque facade and asymmetrical bell-towers of the late 18th-century cathedral are the square’s top attraction. Its interior is surprisingly plain, but it once held the remains­ of Christopher Columbus. Religious services are held here. It has been declared a National Monument.

The Museo de Arte Colonial (Colonial Art Museum) is housed within the oldest construction in Old Havana, the Condes de Casa Bayona Palace, a mansion rebuilt in 1720 by Cuban Governor, Don Luis Chachón. The palace’s Classical patio and coffered ceiling made intricately of wood stand out within this construction. The palace boasts a wonderful location, right in front of the San Cristóbal de La Habana Cathedral. This small museum has a Colonial furniture and decorative art exhibition, amongst which will stand out some pottery with Colonial Cuba motifs, as well as several scenes of Colonial dining rooms and a fantastic collection of ornamental flowers.

Situated in the former Presidential Palace (1920-1960), the Museum of the Revolution is a colorful building of a large dome and a mixture of styles. A detailed panorama of the struggle undertaken by the Cuban people in order to obtain its freedom is available in its 38 rooms. Its outdoor areas feature the Granma Memorial, where visitors can see, protected by an enormous glass case, the boat on which Fidel Castro and more than eighty combatants returned to Cuba from exile in Mexico to recommence the fight for the country's independence.

The Cannon Blast ceremony (El Cañonazo de las Nueve) is one of the oldest and attractive traditions of Havana. In colonial days, the shots signalled the closing of the gates of the walled city and the rising of the chain across the entrance to the harbour. The tradition of firing a cannon every night at 9:00 pm was kept even after the wall was torn down and is still used for checking your watch.
