I was mainly wondering why noone else claimed the tavern or demolished it to make room for a new building considering that the city was probably growing between 2700 BC and 2075 BC. Looking at the photo it seems the tavern was found in the top soil layer with nothing above it. But perhaps the photo looks like that because there have been several excavations since 1887. Or maybe the photo just shows some random building...
