I can help you decipher the directions. Die Straße runter means "Street downhill", so it seems like you're looking for a store located at the base of the hill or at the bottom of the street. A Straße (street) is just a street name, so it's not a specific store. However, Über die Straße (over the street) indicates "through the street". A Littfasssäule (a small pillar or column) is a building, so it suggests that the next building or store is inside or near a building, possibly a church. Daher, based on this interpretation, the last step is that "quer über den Markt" (over the market) means to approach it directly. der Supermarkt ist direkt dahinter (the supermarket is directly ahead of it). So, the final answer is: LOCATION: der Supermarkt
