Plaza de Armas surrounds a statue of the patriot Céspedes and is ringed by shaded marble benches and second-hand bookstalls. This square, founding in 1519, was the city's first open space, around which the most important political, military, religious and civil institutions were located. The palaces that surrounded it during the 18th century are worthy exponents of Cuban Baroque architecture. On the square’s eastern side a small neoclassical temple, El Templete, marks the spot where the first Catholic mass was celebrated in 1519. Next door is one of the city’s most luxurious hotels, Hotel Santa Isabel. To the north, the squat but angular and moated Castillo de la Real Fuerza (Fort of the Royal Forces) is one of the oldest forts in the Americas.  

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.

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.

Currently the venue of the Office of the Historian of Havana, the palace was built in 1776 and has been given several functions: official residence of the Spanish governors of the island from 1781 to 1899 and of the presidency of the republic from 1902 to 1920. The City Museum currently occupies part of the sumptuous halls with permanent exhibition of arts and history of the colonial times and of the beginnings of the 20 th century. The museum exhibits valuable treasures such as: the first Cuban flag, personal effects of the heroes of Cuba: Jose Martí, Máximo Gómez and Antonio Maceo together with a priceless collection of colonial furniture, carriages and other works of art.
