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.

The Gran Teatro de La Habana Alicia Alonso (Great Theatre of Havana Alicia Alonso) is one of the architectural jewelry of Havana. It has an incredible neo-baroque façade with the signature of the Belgian architect Paul Belau. Located in a building known as the Galician Centre of Havana, it was inaugurated in 1915 and at the beginnings it was named Tacón Theatre. Not only in its façade there are evidences of its exquisiteness, but also its indoors halls show the luxury and elegance of the time. Its stages have shown the better artistic representations of all times, with outstanding personalities during its history (Sara Bernhardth, Enrico Caruso, Alicia Alonso) The theatre has been home to the Cuban National Ballet and, the main stage of the International Ballet Festival of Havana. Its facilities include theatres, a concert hall, conference rooms, and a video screening room, as well as an art gallery, a choral centre, and several rehearsal halls for danzarias groups and dance companies.

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.
