Bighouse

(Actually, there were several different styles of bighouses, including an underground one which was roofed over—a similar type of architecture is currently popular in some parts of the country as an energy-efficient house.)[…]Mask dancers may use the bighouse for some ceremonies and rituals, but may perform at functions anywhere.

This explains symbolism such as that of the Delaware bighouses, which were constructed to mimic the different levels of the cosmos.[…]The symbolism of the bighouse reminded the Delaware that all their activities lay open to the powers that had made the world.
