Cárdenas is a maritime port town on the level and somewhat marshy shore of a spacious bay of the northern coast of the island (Bay of Cárdenas), sheltered by a long promontory (Hicacos peninsula, including the Varadero beach resort). The city lies between the sea and hills.
A large quantity of asphalt has been taken from the bed of the harbour. A flow of fresh water from the bed of the harbour is another peculiar feature; it presumably comes from the outlets of subterranean rivers.
There are mostly narrow streets, various squares (including the Plaza de Colón, with a bronze statue of Columbus given to the city by Queen Isabella II. and erected in 1862) and substantial and elegant business and public buildings, including the ornate parish church designed by Architect Rafael Carrerá, who also built the famous Palacio Aldama in Central Havana.en.wikipedia.org
