Hi everyone, i found something like a cave entrance(?) i don't know o.o

its a nice stone entrance with a few corpses around it and a blue circle -> kind of a area switch i know from other games and inside is a statue thats an angel o.o
but nothing happens when i enter it and there is nowhere to go inside :o
soo is it coming with an patch or has it some other purpose?

greetings devilAby
