Tips from the Community
The Church of San Antón is a Catholic church located in the Old Town neighbourhood of Bilbao, Spain. It is dedicated to Anthony the Great, known as San Antón in Spanish. It is featured, along with the San Antón Bridge, in the city's coat of arms. The estuary of Bilbao flows next to it. The church was built at the end of the 15th century on a plot where there had been a warehouse for three hundred years. It is considered an asset of cultural interest since 17 July 1984, in the category "National Historic-Artistic Monument". In 1774 the construction of the present Belfry Tower was begun by Gabriel de Capelastegui, replacing an earlier structure. The tower has a quadrangular body that rises near the central roof. Above it is the belfry crowned by a dome and a lantern, and with auctions in the weathercock. It has a shining Baroque dieciochesco style, being one of the best examples of the whole Basque Country. The weathercock dates back to 1775, specifically it was made on 7 December 1775 Throughout history this church has suffered damage and was closed twice. The main source of damage was flooding from the Nervión river. The last flood was in 1983 and resulted in furniture, drag doors and railings inside the church being destroyed. The church has also suffered damage through bombing and fire during war, especially during the Carlist war. During this war, the church was forced to close as it was used for military logistics.

On top stands the 'Ermita San Juan de Gaztelugatxe (in Basque: Kasteilfelsen), an old 10th-century chapel dedicated to John the Baptist, once a monastery of the Knights Templar. The sea, but also battles and fires, has destroyed the chapel more than once. Through the centuries, the church has been rebuilt and renovated several times.
