This bridge, which connects the neighborhoods of Toral and Merayo, is built over the Oza River and combines traditional architecture with the natural beauty of the area. Its slate and limestone masonry structure evokes a sense of historical authenticity. Although it is not as famous as other medieval bridges, its uniqueness and location make it an interesting place to visit. 😊
