Personally I love the idea that there is something hidden lying below some ruined building. In this map there are ruins of an temple on a small hill and then the hidden caverns and a temple below it.
Also, this month I ended up drawing three maps with a row of five statues. These maps can be easily used together for a longer adventure or even a mini-campaign with this common theme.
Two versions of the map (very high resolution) included with this post.
