Sandomierz Megadungeon Architecture

Old Town, Sandomierz

Nathan & noisms recently linked to a Megadungeon design guide. Some of the great maps there gave me the dungeon design bug, so I threw together the map below.  Basically I took a tourist map for the Old Town of Sandomierz, highlighted the relevant buildings for Polish Resistance, and added a side-view of different dungeon sections.  It starts with the Basement Level but then goes deeper.

I'm not sure exactly how to make this work with the Ad-Hoc Dungeon Generator.

Oh, and Life immitates Art.  Apparently the Old Town really does have an extensive tunnel system up-to 12m deep in some parts.
