Przemyśl's cathedral, particularly its 71m-high freestanding bell tower , lords over the upper (southern) end of the Rynek. There's been a church up here since at least the 12th and 13th centuries. The interior is impressive, but be sure to visit the crypts in the basement for a fascinating exhibit on burial customs, some actual crypts and the exposed wall of the original 12th-century rotunda. You can climb the bell tower, though unfortunately the windows are closed at the top.
