Koreshan State Historic Site, State historic park in Estero, Lee County, United States

Koreshan State Historic Site is a park containing restored buildings, gardens, and natural areas in southwest Florida. The 135-acre property spans along the Estero River and features 11 structures along with planted grounds and walking paths.

Dr. Cyrus Teed founded the Koreshan Unity religious community here in 1893. The settlement remained active until 1961, when its last members deeded the land to the state of Florida. It was added to the National Register of Historic Places on May 4, 1976, as the Koreshan Unity Settlement Historic District.

Residents cultivated extensive gardens and used the settlement for printing and craft work that reflected their daily life. The buildings display a blend of Victorian design and local Florida construction styles that remain visible today.

The site offers hiking trails, boat access, fishing spots, and camping for visitors with various interests. Guided tours through the historic buildings run regularly and provide detailed insight into the former settlement.

The Koreshans planted an Araucaria bidwillii, a Queensland native whose seed pods are as large as a football, along with African sausage trees and Japanese bamboo brought from the Edison and Ford Winter Estates. Gopher tortoises, bobcats and American alligators live in the surrounding pine flatwoods.
