The Cathedral de San Cristobal de la Habana sits on the eastern side of the "Plaza de la Cathedral". Its Baroque facade is simultaneously intimate and imposing, and one of the two towers is visibly larger, creating a pleasing asymmetry. The two bells in the taller, thicker tower are said to have been cast with gold and silver mixed into the bronze, giving them their sweet tone. As with many churches in the city, the building material of Havana Cathedral includes coral, cut and hauled from the edge of the sea by slaves. Fossils of marine flora and fauna can be seen in the stone of the cathedral.
The Cathedral is said to be the only example of a baroque facade that was designed with asymmetrical features - one of the towers is wider than the other. This particular feature was conceived in order to allow the water that tended to accumulate on the plaza to freely flow through the streets during the colonial period, when it was built.
There is a very nice restaurant and bar in the plaza, El Patio. It's a nice spot to relax with a drink and nice food.
