Hall
From King Arthur's Gold Wiki
A big, capturable building that acts as spawn point, item/resource storing, research building and win condition. Go inside to capture, build workshops nearby, kick the enemy out of all their halls to win. There are usually 2-5 halls on a map, but there can be as many as the map creator chooses. On vanilla maps, halls currently start neutral, but you can use the blue/red spawn pixels for already converted halls.
