Say a prayer, bow your head and perhaps even light a candle in Old Cathedral. This majestic religious building may not be open 24/7, so check ahead for hours if you'd like to go inside.
Old Cathedral is free to visit, so you can have a fun day out in Altstadtviertel without getting out your wallet. When you're done at this principal church, take a look at some of the area's other popular locations. Linz Castle Museum, Lentos Art Museum and St. Martins Church won't disappoint.
