St Nicholas Church in the Old Town square, which is quite different to the other St Nicholas Church in the Lesser Town. Both are Baroque churches, but each has its own character. The Old Town church was built in the early 1700s and, even if you don't go inside, have a look at the beautiful metalwork on the exterior of the main entrance door. Quite stunning! Inside, frescoes, stained glass, and an exquisite chandelier.
