As it stood in 1700
What Castillo de Santa Catalina looked like in its prime.
Low, compact coastal bastion-fort with thick pale stone curtain walls forming an irregular polygon; several angular, gun-embrasured bastions project toward the sea. The roofline is dominated by continuous parapets and walkways rather than towers. The fort sits on a rocky waterfront promontory with water on at least one side. Inside the walls a broad parade ground is ringed by single-storey service buildings under the ramparts; in its prime the stonework and embrasures are intact and unbroken.
Its story
The story of Castillo de Santa Catalina.
After the Anglo-Dutch assault on Cádiz in 1596, Philip II ordered a defensive fortress for La Caleta by royal decree of October 1597, to plans by the engineer Cristóbal de Rojas. Built out into the sea on breakwaters, the fort took a pentagonal, Italian-influenced plan whose star points jut into the water; Rojas died before his full design was realised.
Under Charles II a chapel dedicated to St Catherine of Alexandria and the Immaculate Conception was added with its sacristy in 1693. In 1769 Charles III turned the castle into a military prison for prominent captives: the Mexican independence leader Mariano Abasolo died here in 1816, and the British officer John Downie was held from 1820 to 1823 for supporting Ferdinand VII.
The fort remained in military hands into the late 20th century — some of those implicated in the attempted coup of 23 February 1981 were confined here — until the Ministry of Defence gave it up in 1991. Declared a site of cultural interest in 1993, it now hosts cultural events including the Alcances film festival.
