The castle is situated near the village’s Protestant church, by the banks of the Aranyos river. The castle was first mentioned in a document from 1268, when it was owned by the Gerendi family. In 1597 due to Turkish invasion they lost the ownership. The estate with the castle became the property of the Jósika family and the Sarmasaghy family.
Obreja is a late Romanian serf-village, which was from the beginning in the hands of the noble family Esterházy. Sometime in the second half of the 19th century it became the property of the Wesselényi family, being owned by br. Wesselényi (V) Miklós (1845-1916). After the nationalization a special school functioned in the castle, and then an orphanage. In 2003, the Greek-Catholic Church has reclaimed the building, so today it houses the sisterhood. The new owners placed a tasteless metal roof on top of the building.
