This is a battle map that might be an encounter in a steampunk setting, or even in the world of Ravnica or Eberron. Even though the map title says "iron golem" the construct might be as well a warforged or a clockwork construct, like a nimblewright.
This map pack includes a dozen different map versions. Each map is 13x13 squares and 140px per square.
A layered 300 dpi .tiff file is available at the Hero Archive for Hero and higher tier patrons.
