It is located 2.5 km south of the walls of the Outer town amidst Patleina Nature Reserve. Most probably the patron of the monastery had been Pantеleimon – a saint and a healer, whose name was given to the whole area. The complex consists of a crossed-dome church with rich decoration and chain buildings situated around it that served various functions. An ossuary with six burial chambers was excavated north of the temple while southwest of it some workshops for producing painted ceramics were found. The workshops in the monastery area and the ones in the northern part of the region show that one of the centres for producing Preslav painted ceramics was located in Patleina place. The famous icon of St. Theodore, found in one of the premises west of the ossuary serves as evidence for the high artistic value of the centre’s output.
