Although it was first built in ancient times, the present building dates back to the 15th century. The Petrela Castle was part of the signaling and defense system of the Kruja Castle. The castles signaled to each other by means of fires. During Skanderbeg’s fight against the Ottomans, the Petrela Castle used to be under the command of Mamica Kastrioti, Skanderbeg's sister.
Today there is a restaurant inside the castle. The castle offers spectacular views of the Erzen valley, the hills, olive groves, and surrounding mountains.
