Laredo’s compact old quarter still resembles the medieval Castilian port that protected merchants and sailors from pirates raiding the northern coast.

On this walking tour, you’ll follow streets that once connected the walled centre with the working port below, and discover how this strategic harbor town evolved from a fortified enclosure into a seaside destination.

This circular tour starts and ends at Pisuco Salvé guesthouse on Calle Ruamayor, the medieval main street where carts were loaded with wool, iron, and wine bound for Flanders. You’ll pass through sections of the outer wall, now integrated into modern buildings, and descend through the Puerta de San Lorenzo, where the walled town gave way to expansion and growth.
