The Church of St. Michael is situated North-West of Babino Polje, on the Island of Mljet. This part of Island is called after the patron saint of the Church (Sutmiho and Sutmiholjska bay). The Church was mentioned in 1430 as a Benedictine Church where monks resided upon arrival on this Island.
There is no information on the original ground plan and affiliation type of the Church. The construction of the early medieval church is indicated by fragments with plaited ornaments (a pilaster from the altar screen and a lintel with an inscription in Latin) that can be dated to the 10th or the 11th century.
