If you walk towards the city exit gates, by the large tower, there is a small ledge by the last house on your left before that tower. Walk on the ledge and around that house until you come to a wall. It is possible to jump out and around it - might take you a few minutes to get the hang of it, and might take a few seconds. It\'s not really a \"secret\" entrance, just one that is blocked off.
Also, you could\'ve just posted this in that other thread ;)
