St. Mary’s Monastery is the smallest monastery in the village of Arbanasi. It is located in the northwestern part of the village, about 5 km from Veliko Tarnovo. It was founded in the Middle Ages during the period of the Second Bulgarian Kingdom. It was abandoned during the Ottoman rule due to several raids. The destruction of the Kurds and the spread of bandits, was restored at the end of the seventeenth century when the new church was built, which is still preserved to this day, and later (at the beginning of the eighteenth century) residential buildings were added and the monastery resumed its work. The monastery consists of a small church with two halls and the large Church of the Holy Trinity in the northern part. The churches contain very valuable frescoes and icons, the most important of which is the icon of St. Mary engraved in silver. Today, the monastery serves as a monastery for nuns.
