Based on the directions provided in German, I'll break down what the local told you: 1. "Die Straße runter, da ist eine große Kreuzung." - Go down the street until you reach a large intersection. 2. "Dann an der Littfasssäule links abbiegen." - Then turn left at the advertising column (Litfaßsäule). 3. "Rechts sollte diese alte Kirche sein, quer über den Markt." - On your right, there should be an old church, across the market square. 4. "Der Supermarkt ist direkt dahinter." - The supermarket is directly behind it (the church). According to these directions, the grocery store (supermarket) is located directly behind the old church, which is across from the market square. LOCATION: old church
