Frustratingly closed to the public at the time of writing, the Castle of San Sebastián is a major piece of cultural history in Cádiz. The history of this place stretches all the way back to the Greek Gods, although a humble 15th century chapel marks the physical beginning of its story, a little chapel for those suffering (read; dying) with the plague. A castle came in the 17th century, a castle that took on extra defensive importance when Cádiz entered its golden period a century later. The castle was connected to the city as late as the 19th century, and the walk out remains one of the most exciting strolls in the city. Here’s hoping the necessary work is done on the castle in order to make it visitor-friendly.
