Kostel svatého Mikuláše
The plain but imposing Church of St. Nicholas was begun in 1230, when it belonged to the Order of Teutonic Knights. Tinkering over the centuries added an impressive Gothic portal and a baroque interior. Just inside the Gothic entrance is a wonderfully faded plaque commemorating the diamond jubilee of Habsburg emperor Franz Joseph in 1908. The church was restored in 2016, and you can now visit the crypt, which has exhibitions, and the south tower, which has a panoramic view of the city.
