From publisher blurb:
Dungeon Entrances is a printable dungeon floorplan compatible with any RPG/Dungeon-Crawl game. It can be used as a standalone gameboard, or combined with any same-scale tileset.
Dungeon Entrances is a geomorphic set, comprising 4 10x10 square battlemaps which can be arranged in multiple layouts. Each tile features corridors and rooms in a dungeon setting with a different style of entrance - large grand doors, broken walls, sunken courtyards and more.
Also included is a set of 300dpi full size jpgs, for poster printing or VTT, in both gridded and non-gridded versions. (n.b. gridless version only available as full jpeg)
