A New Marking
The tunnel seems to go through cycles of dry and then damp conditions, with our weekly maintenance we have been keeping up with clearing the small pockets of water and thankfully there has been no major flooding since we got the tunnel dry. Depending on what cycle you visit the tunnel the markings left by the workers or Germans can be easier or more difficult to see. In an area of the tunnel that is normally dry but recently became damp, we have noticed the faint markings of a circle and what seems to be a three numbers above it. It is in the same format we have seen in other areas but in the current cycle it is hard to read. We will be keeping an eye on it to see if it is easier to read when it drys.
