The Old Town Hall stands on the Paseo del Reloj. This single-nave building was built in the 15th century as a charity hospital, known as the “Hospital de los Ángeles”. It was transformed into a shrine in the 17th century. A 27-metre high, neo-Mudejar style tower was added in 1905. The tower takes its name from the high-precision clock on two of its sides. It is crowned by a bell. This tower is the iconic symbol of Almadén de la Plata. It currently houses municipal offices, including the Plenary Hall and the Department of Social Affairs.
The building was declared a Site of Cultural Interest by the Regional Ministry of Culture of the Andalusian Government on 26 November 2007.
