Castrojeriz Castle

Strategically located on the hill overlooking the town is the fortress whose origins date back to a Roman tower of the S. I a d C. It is located on the site occupied by the ancient Iberian Romanized castro of the Murgobos, whose name was Sisaraca. The remains from the time of Emperor Augustus can still be admired today among the constructions of later times and its purpose was to guard the crossroads of roads that went to Segisamón and Clunia Sulpicia. Destroyed and rebuilt again in the 9th century, as part of the reconquest, it was inhabited by Pedro I El Cruel and it was here that he held his aunt Leonor of Castile prisoner, whom he had executed in 1359. Largely destroyed again in the great Lisbon earthquake of 1755 and in the war of independence, today its ruins have been consolidated since 2013. Two viewpoints were built and are accessed through the medieval stairs that are still preserved. It has structures enabled for tourism with explanatory plaques.
