New Haven District Campground

The New Haven District Campground, also known as the Plainville Campground, is a historic Methodist camp meeting site in Plainville, Connecticut. Opened in 1865, the campground was used by Connecticut Methodists to partake in the 19th-century trend of religious and recreational camp meetings. Despite their original purpose as revivalist gatherings, camp meetings became a popular leisure destination for the middle class in the 19th century due to their moral nature and affordability. The campground consists of 89 cottages, built as permanent replacements for the site's original tents, which surround a central preaching area in the camp meeting's traditional circular pattern. At the height of its popularity, the campsite had its own railroad station and spurred the local economy in what was at the time a rural area. The campground lost its religious affiliation in 1957, though the cottages are still used as summer homes.

The campground was added to the National Register of Historic Places on May 19, 1980.
