I've just got home after having bumped into a BT engineer who told me the location of M.E's poser about the telephone exchange in Allanson Road, Rhos, hastily logged on with the answer and found out that Hollins had beaten me to it after the latest clues which were posted after I left home.
Never mind, here is a fairly easy one after the last one!. Where would you find this in North Wales? (And for a bonus point what is currently situated next to it and why?)
