The most important historical monument in the nearby Dobre Miasto is the 14th century collegiate church, the second largest (after the Frombork cathedral) church in this region. Enormous Gothic church and fragments of the defensive walls. From here it is not far to Lidzbark Warminski, which used to be the Episcopal seat of the bishop of Warmia. One of these was Lukas Watzenrode, the uncle of Nicolaus Copernicus, with whom the future astronomer stayed as his physician and secretary. All the old part of the town is of historic interest, especially the Gothic bishops castle, which is a splendid example of medieval defensive building and which now houses a branch section of the Museum of Warmia and Mazuria.
