Mirabel Castle was built in the 15th century on Cerro del Acero, which is why it is also known as the Peña del Acero castle. It is currently very deteriorated and only a few vestiges can be seen, such as a large brick vault and some walls.
The castle of Mirabel or Peña del Acero, is a defensive building and its origins date back to the 15th century. It is located near the town of Mirabel, on top of the Cerro del "Acero" hill.
