My campaigns have never featured a lot of traditional RPG dungeon crawls; I’ve always felt they were a little contrived and disrupted the grittier/realistic feel I was striving. Instead of stocked underground mazes filled with traps, puzzles and commensurate rewards I challenge my players with fortresses, strongholds, castles and lairs. Creative architecture is not my strongest skill, so I look to real life examples for ideas and templates. A google image search under “archaeological floorplans” generates a wealth of great layouts that can be printed and used for gaming. Most of these archaeological layouts are for ancient sites destroyed years ago and forensically recreated from the remnants of historical records, foundation stones and building science so I’m always excited to see an intact site.
