The Mongolian yurt, or ger, is a round, nominally portable, self-supporting structure suitable for
camping in comfort.
It does not rely on ropes or stakes to hold itself up; rather, the walls, rafters,
roof ring, and tensioning bands all work against each other, in a marvel of physics and
engineering, to keep the structure standing.
It is thus an especially appealing structure for
camping events where space is at a premium.
provides useful living space -- no extended ropes are required as they are for pavilions.
