This series from 0one Games provides generic maps of various locations in both traditional blue (if you remember the maps accompanying early Advanced Dungeons & Dragons modules) and black lineart. They are designed to be easy to customise, and to drop into your campaign world wherever you have need of the location depicted - and yet are interesting and full of ideas for adventure, even if you don't have one planned for that place.
As well as a generic range of individual locations, there are several complete towns plus more detailed treatments of areas and individual buildings in each, as well as the Blueprint Backdrops, which provide residents and story ideas for selected buildings in The Great City. Whilst they were orignially created with Dungeons & Dragons 3e and the Pathfinder RPG rulesets in mind, they'll work well whatever fantasy game you are playing.
The newest line, Deep Blues, expands the range to other than fantasy beginning with several 19th/20th century plans.
