Built in 1519, Plaza de Armas (Weapons Square) , with it´s neoclassical architecture,
is the most ancient square of Havana.
Around it, there are the most important monuments, like Castillo de la Real Fuerza.

El Malecón is the oceanside pedestrian avenue that runs along the north coast of the city, beside the seawall, all the way from the Castillo de San Salvador de la Punta in La Habana Vieja to the Almendares River that separates Vedado from Miramar. The Malecón is the most popular avenue of La Habana and it is a great place to spend some time strolling and lingering, enjoying a sunset in a typical Cuban setting. 
 

Placed in Vedado,the actual square itself may be a bit of a letdown, a huge (72,000 square meter) empty asphalt square with no shade. It is one thing to see it overcrowed on May Day and another during most of the other days of the year.
The square is being dominated by the José Martí Monument and the famous image of Che Guevara taken by photographer Korda and turned into a relief sculpture by Enrique Avila on the Ministry of Interior building. Inside the monument there is a museum dedicated to Cuba´s writer, poet and national hero in War of Independence. From there you can take a mirrored lift which will bring you up to the highest point in  Havana.

There is a second “Music House” in Miramar, smaller and quite pricy (10.00CUC entrance plus an extra few CUCs to avoid queuing, to use the toilet etc) and in general the atmosphere is a bit tacky.
