How Mongols Built the Ger (Yurt): Engineering a Nomadic Home
The ger (Mongolian) or yurt (Turkic/Russian) is a masterpiece of portable architecture, perfected over millennia on the Central Asian steppe.
Structure & Components
| Part | Mongolian | Material & Function |
|---|
| Crown / Toono | Toono | Central ring; smoke vent + light; supports roof poles |
| Roof Poles | Uni | ~80–100 bent poles; radiate from crown to wall |
| Wall Lattice | Khana | Collapsible trellis (willow/birch); determines diameter |
| Door Frame | Bosgo | Wooden; always faces South (away from prevailing NW wind) |
| Door | Khaalga | Wood or felt flap; colorful painted symbols |
| Felt Cover | Esgen | Sheep wool felt; 2–3 layers; waterproofed with tallow |
| Outer Cover | Orkh | White cotton canvas; protects felt; ties down |
| Tension Band | Khts | Horsehair/wool rope; cinches roof poles to wall — structural key |
| Floor | Shal | Carpets, felts, sometimes raised platform |
Assembly Process (30–60 min)
- Lay out door frame & threshold.
- Unfold khana sections; connect into circle; lash to door frame.
- Raise toono on two support posts (bagana).
- Insert uni poles into toono slots; outer ends rest on khana.
- Wrap esgen (felt) over frame; secure with khts.
- Cover with orkh; tie down to ground stakes.
- Install stove pipe through toono flap.
Interior Layout (Traditional)
- North (opposite door): Altar/shrine, honored guest seating.
- East (left): Men's side — tools, tack, airag (fermented mare's milk).
- West (right): Women's side — kitchen, storage, family sleeping.
- Center: Stove (zuukh) — heart of home; fire never fully extinguished.
Why It Works
- Thermodynamics: Felt insulates -40°C to +40°C; stove heats fast.
- Wind Resistance: Aerodynamic cone; tension band prevents lift.
- Portability: 2–3 camels/yaks or 1 truck; family moves in hours.
- Repairability: Every part replaceable from herd/forest.
The ger is not a tent—it's a mobile home engineered for extreme continental climate.
