Constructed with a combination of rock, mortar and wood, these doorways at the Pueblo Bonito lead to the heart of the great house.
The thick wooden transoms reinforce the opening of the doorways and are probably the reason the doorways have not collapsed.
Pueblo Bonito has had the influence of many generations of builders over several centuries having been constructed between AD 830 and AD 1250.
