Traitors Gate
Traitors Gate 1s the exit where Dimwell Street meets the city walls. According to the map contained in The Compleat Ankh-Morpork, this is the exit point for those wishing to get to Jowser's Cove and that point in the Central Continent, opposite Al-Kinte in Klatch, which is as far Turnwise as it is possible to get without getting your feet wet. Holy Wood is apparently in this region somewhere.
