You can actually go left or right when your inside. So instead of just going straight, take one step to go inside then turn left or right.

uhh enter the other way such as this
amity square enter 1----------------------amity square enter 2
go to the other door thingy mabober

if i remember correctly if you keep going to the right in the ruins then you should keep teleporting to a different one and left takes you to the original one you entered
