Castell de la Trinitat

Castell de la Trinitat is located on the Gulf of Roses, Alt Empordà comarca, Province of Girona, Catalonia, Spain.

[1] Work began on January 2, 1544 and the castle was completed in mid 1551 under the Spanish engineer Luis Pizano.

In 1808, it was defended for twelve days by Royal Navy sailors and Royal Marines under the command of Captain Thomas, Lord Cochrane, supported by Catalan militia and regulars, and the damage inflicted by the besieging French and Italian artillery was compounded by an immense explosion of gunpowder barrels from Cochrane's frigate HMS Imperieuse, laid by him to deny the investing French control of the sea approaches to the Bay of Rosas.

[3] The construction is about 18–20 metres high, with thick walls, and designed to house a garrison of about 350 men.

Derelict for nearly 200 years, it underwent restoration amounting to about 2 million euros between 2002 and 2010,[4] and a museum was established at the site.
