Castillo de San Sebastián, Maritime fortress in Cádiz, Spain
Castillo de San Sebastián is a maritime fortress located on a small island at the end of La Caleta beach, connected to the city by a stone causeway. The structure has thick defensive walls arranged in a square pattern with a prominent lighthouse rising from its center.
Construction began in 1706 as a fortified defense for the northern side of Cádiz, replacing a chapel founded by Venetian sailors in 1457. Over time, the fortress shifted from a military installation to an important landmark for the city's heritage.
The fortress holds regular exhibitions and concerts that connect it to daily life in the city. These events help locals and visitors understand its importance to Cádiz's cultural identity.
The fortress opens daily from 09:00 to 13:00 and is reached by walking along the Paseo Fernando Quiñones causeway that extends into the sea. Wear comfortable shoes as the exposed walkway can become slippery during wet conditions.
A 41-meter-high electric lighthouse built in 1908 stands on the foundation of an ancient Moorish watchtower. At night, this tower beams across the bay and creates a recognizable silhouette that has served as a navigation landmark for more than a century.
