The Clock Tower of Chiclana de la Frontera, , is one of the symbolic buildings in the town. It was originally built in the 18th century as one of the ancient doors of the town, and formed part of the bygone Town Hall. It is located in the Plaza Mayor, next to the Church of San Juan Bautista. The church does not have a bell so this religious use was bestowed on the clock tower. The two buildings are located in Plaza Mayor.
