Kastellinlinna in Pattijoki is the the largest of the jätinkirkko ("Giant’s Church") formations in Finland.
It is a stone formations in the shape of an oval, built around 3,000-1,600 B.C. It's not known for sure for which purpose these stone structures were built. Most probably they were campsites used by seal hunters. Though others suggest that they might have been used as ritual sites.
This is guite small basement bar at the old town of Raahe, but there's live music almost every night and it have pretty goof atmosphere. This place is absolute place to visit.
There might be some hippie-kind of people :D Also students used to be there.
Used to known before as Panimo (brewery)
