I think the words "Dark Tourism" suits, however, I would lile to visit such a place. It would be so interesting as I visited one in Milano, Cimitero Monumentale di Milano. It is very very interesting, I felt myself in a horror movie :)
Thanks for the post mate!
I just googled out that Milan cemetery, very interesting place. But ossuaries are another level. It´s just skulls and bones everywhere around you. Honestly, I don´t even know why such places were built in the past... Glad to know that you enjoyed this post though ;) Cheers!
