In Overlord, Carne Village has a big silver area towards the middle. What is it? (picture in description) It looks kind of like a lake or a large structure. Maybe it's just an opening with stone, dirt, or clay as the ground. Do you know?
If I remember correctly, that was a tower where the bell is situated. 


  When the bell in the middle of the village square rang to signal noon, everyone would take a break for lunch time.


And no, that's not a lake. That's just a large open area with no structures in it apart from the bell.
