The oldest bastioned fortress in the New World, completed 1577. It now houses Cuba's premier maritime museum with excellent exhibits of Cuba’s maritime past, from pre-Columbian days through to the 18th century with the Royal Shipyard of Havana, one of the largest in the world which built nearly 200 ships for the Spanish Crown. The museum includes a huge model of Santisima Trinidad, one of the largest ships in the world during the 18th century. The fort is also a great location for viewing the harbour and city skyline.
The Castillo de la Real Fuerza is a bastion fort on the western side of the harbour in Havana, Cuba, set back from the entrance, and bordering the Plaza de Armas. Originally built to defend Havana against attack by pirates, it was not strategically located, being too far inside the bay, and instead was adopted as the residence of the Governor of Havana. The fort is considered to be the oldest stone fort in the Americas, and was listed in 1982 as part of the UNESCO World Heritage Site of "Old Havana and its Fortifications".

Spacious and elegant, the square is surrounded by baroque constructions that give it an authentic colonial milieu. It was laid out during the 1600s, replacing an old plaza which acted as the center of religious, administrative and military activity. Until the mid-18th century, it was used for military exercises and parades. After its remodeling between the years 1771-1838, it became a favored meeting spot for the city's wealthy. Today it is also known as Céspedes Park, in honor of the country's Founding Father, whose monument stands at its center. This square is one of the most outstanding in the city, enlivened by vendors of antiques and classical books on Latin American and world literature. Attractions of remarkable historical value lay around the square such as the capok tree (Ceiba) under which the first mass for the city's founding was officiated in 1519.

Museo del Ron Havana Club
Go on a guided tour of Havana Club, one of Cuba's most famous rums. Most of the exhibits are subtitled in English and are fairly self-explanatory.
A well-restored fort of the 18th century that holds two one-room exhibitions about arms and Che Guevara. Every evening there is a cannon ceremony where they fire over the Havana harbour. To get there take any bus (ex. from the Parque the la Fraternidad) that crosses the tunnel and get off right after it. Walk about 600 m to the entrance. On your way you can also stop at the smaller Castillo de los Tres Santos Reyes Magnis del Morro next to the tunnel.
