An odd religious cult lived in Estero, Florida, from 1894 to 1961, with its heyday in the first two decades. Followers of Cyrus Teed believed that the earth existed on the INSIDE of a hollow sphere. They also demanded celibacy, a sure way to assure that the cult would die out.
The State received the Koreshan State Historic Site in 1961 as a gift from the last Koreshans.
I visited the day before a quilt show. The organizers spread quilts around one of the buildings.
