The heart and soul of Havana is the old town Habana Vieja, declared a Heritage of Mankind Site in 1982 by UNESCO. It was keen to preserve the beauty of its architecture and promote the historical importance of its role within the region.

Some interesting places to visit are:

• Plaza de Armas, centred around a statue of the patriot Cespedes and emcompassed by shaded marble benches and second-hand booksellers, is the first public square built in the city.
• Plaza de la Catedral is perhaps the most beautiful square in the Caribbean which is surrounded by examples of the finest baroque architecture in the country.
• El Templete, small neoclassical temple which marks the spot where the first Mass was said in 1519
  
  Castillo de la Real Fuerza is one of the oldest forts in the Americas, it holds modern art exhibitions downstairs and the battlements afford good views over the harbour.
• Palacio de los Capitanes Generales, the seat of government and governor's residence was transferred from the fort to the built. The presidential palace and then the municipal palace until Castro seized power it is now Museo de la Ciudad de la Habana.
• Museo de Arte Colonial, fine palace constructed in 1720, its yellow courtyard and little-altered architectural features are complemented by a large collection of 17th- and 18th-century furniture.
• Calle Obispo is Old Havana's most important and smartest thoroughfare, pedestrianized with missile heads as bollards.
