Torres de Serranos, also known as Serranos Towers, are one of the best-preserved gates of the former medieval city wall of Valencia, Spain. Constructed in the late 14th century in Valencian Gothic style, these imposing twin towers served as the main entrance to the city and were later used as a prison for nobles. Today, visitors can climb to the top for panoramic views of the city, the Turia Gardens, and the surrounding landscape. They're a significant landmark and a great place to start exploring Valencia's historic old town.
