Due to its strategic position right on the Bay of Biscay and on the French border, many armies have tried to conquer this ancient city: from Charlemagne, to various French armies. These skirmishes left an important military legacy in the area that tourists can discover with Free Tours in Hondarribia. The Guadalupe Fortress is a massive 19th-century building that dominates the city's landscape. In the old town, in addition to the fortified walls, one of the must-see places is Santa Maria Gate, a centuries-old stone arch that was once a gateway to the city. Nearby is the Church of Santa María de la Asunción y del Manzano, an impressive Gothic temple so fortified that it looks more like a fortress than a religious temple. In the 19th century, the city became a popular vacation spot for the European bourgeoisie. So, there are plenty of charming avenues and even old casinos to explore with Hondarribia Free Walking Tours.
