San Martín de Valdeiglesias has a rich history dating back to the Middle Ages. Its name refers to the town’s historical association with the church (“Valdeiglesias” translates to “Valley of Churches”). Over the centuries, the town has seen influences from the Romans, Visigoths, and Moors, contributing to its diverse cultural heritage. However, it was during the Christian Reconquista that San Martín truly began to flourish, becoming a vital stop along pilgrimage routes and trade paths.
One of the town’s most significant historical sites is the Castle of Coracera, a medieval fortress that dates back to the 15th century. The castle was originally built by Álvaro de Luna, a prominent figure in Castilian history. Today, it serves as a cultural and historical venue, offering guided tours, exhibitions, and event spaces.
San Martín de Valdeiglesias is also known for its vibrant local festivals, the most famous being the Fiesta de San Martín, held every November to honor the town’s patron saint. This celebration includes traditional music, dance, and a variety of gastronomic delights. The town also celebrates the Romería de la Virgen de la Nueva, a pilgrimage to honor the Virgin Mary, which attracts visitors from all over the region.
