It is located at Plaza de la Cava, 1, in the town center of Marcilla (Navarra), easily accessible and surrounded by bars and a children's playground. This 15th-century Gothic fortress was built of brick on a stone foundation by Mosén Pierres de Peralta, with material and financial support from Charles III the Noble. It served both as a defensive stronghold and as a palatial residence for the Marquesses of Falces, descendants of Peralta. In 1516, the Marchioness Ana de Velasco saved the castle from being demolished by order of Cardinal Cisneros.

A magical place that hides a history of romanticism that dates back to the 13th century. Inside the Bardenas Reales park, this tower that has been eroded by the scourge of the weather today is a symbol of the region. Built by Sancho el Fuerte in the 13th century, it was originally conceived to protect the border between Navarre and Aragon. Later it was the prison of Princess Blanca of Navarra who was imprisoned by her father Juan II of Aragon for refusing the agreed marriage. The story goes that every night a shepherd came to give the princess food and drink and that when she was released, as a thank you, she herself gave this shepherd the land where her prison was located.
