Two tunnels at old horse tracks. About 50 meters and 30 meters. Firts tunnel is near the road and can be seen from hämeenlinnantie. Other one is backside of the tracks and closer to forest. Adress is hard to explain. It is center of a big hill called Kärpäsenmäki. Check it from googlemaps and you'll see big ring next to hämeenlinnantie/western cemetery. Nowadays there is bmx-course and you might also find some plywood to paint..
Is this wall still safe to paint?
