Ugrovesk
Ugrovesk was a fortified town on the Bug in the western lands of Volhynia. Prince Danylo Romanovych developed it and made it the seat of a bishopric in the early thirteenth century. The bishop's seat was later transferred to Chełm, but the town's monastery of St Daniel remained a notable religious house. The Lithuanian prince Vaišvilkas took monastic vows there, linking the settlement to the turbulent politics of the neighbouring lands.
