A prominent aspect of slave religion was the “brusharbor .”
These brush arbors , hastily constructed “churches” made of a lean-to of tree limbs and branches, had been a prominent part of the southeastern traditional religion.
The brush arbor architecture that became a critical part of the “camp-meetings” of the Second Great Awakening was borrowed from the architecture of the “stomp ground” of southeastern traditional religious practices.83
That Native Americans supported the invisible institution is evidenced in the slave narratives: “Master Frank wasn't no Christian but he would help build brush arbors fer us to have church under and we sho would have big meetings I'll tell you.”84
