Castle of Benabarre Monument · Benabarre, La Ribagorza, Huesca Castle also known as the castle of the Counts of Ribagorza, set along an elongated hill of great height above Benabarre, from which there was visual communication with nearby towns such as Purroy or Pilzán. It rises on a promontory of limestone rock that serves as its foundation, which prevented its walls from being mined — a technique common in the siege of fortresses, consisting of digging a tunnel under the wall to bring it down and open a breach —; it is also surrounded by its own wall, and is reached by stairs protected by a wall. Capital of the former county of Ribagorza until Philip II forced Count Fernando de Gurrea y Aragón in 1591 to renounce it after years of revolts, it was then incorporated into the royal estate; it was declared a Bien de Interés Cultural (Spain's highest level of heritage protection) in 2006.
