Remains of a church can be found on the slope of a mount, to the north of the village of Ošlje, at a location called Bijela lokva. The dedicated saint is unknown, whilst the local people call it “Rotonda”, “Banovi dvori” and “Mirine”. Eight semi-circular apses both from the interior and interior are distributed in a circular confi guration.

The eight-leaf layout has a rectangular narthex (a porch) on the western side, from which the bell- tower once rose. This is the only example in the south Adriatic of a pre- Romanesque building with an eight-leaf layout, above which there used to be a dome. The church is dated to the 9th or 10th century.
