Went to investigate some old tunnels in our local park i got told about.
Never knew they existed until yesterday, and i've lived in the area for 38years
The 2 tunnels run parallel to each other.
I think they could be water outlets for the old mill, then ran into a lake where the park is located now.
Very stonky in places, and averaged about 3foot in height throughout ( lowest was 18inches - belly job ),
except the entrance part - that went to about 10foot high.
Plenty of spiders were inside.
i didn't get to the end due to time, but will find out where it comes from / leads to proper another day.
