Martonyi Monastery, Gothic monastery ruins in Martonyi, Hungary

Martonyi Monastery is a church ruin in Hungary with preserved walls standing in a forest setting. The monastery's church was single-nave, measuring about 26.5 meters long and 12.5 meters wide.

The monastery was founded in 1341 by Martonyi nobles, the sons of Tekes, and the Gothic church was built by 1347. In 1411 János, auxiliary bishop of Eger, consecrated its three altars. Around 1550 it became uninhabitable, like other monasteries in the area, and from the late 16th century it fell into ruin.

The monastery belonged to the Pauline Order, founded in Hungary in the 13th century. The church was dedicated to the Blessed Virgin; in 1411 János, auxiliary bishop of Eger, consecrated its three altars. The site is also called the Three Hills monastery. Visitors can see the reconstructed roof covered with shingles and the rebuilt buttresses.

The site is accessible via a marked forest path beginning from the green asphalt road at the village edge of Martonyi. The trail runs through wooded terrain, so suitable footwear and attention to the pathway are recommended.

Archaeological excavations uncovered 400 carved stone fragments that were integrated into reinforced wall sections during recent restoration work. These recovered pieces show the care taken to preserve the monastery's original material within the repairs.
