Leonardtown is the county seat of St. Mary's County, Maryland. The population was 1,896 at the 2000 census. The College of Southern Maryland maintains a small day campus there; there is both a large public and a Catholic high school, and offices of the county government. St. Mary's Hospital is located in Leonardtown and serves the entire county. Leonardtown is perhaps most famous for the national oyster-shucking championship that occurs annually at the County fairgrounds. Also, the upscale Breton Bay development is just outside of town, notable for both its country club golf course and pool. Leonardtown's population is growing due to the town's proximity to Patuxent River Naval Air Base, as well as from migration out of the Washington, DC area. Several new ethnic restaurants, and an upscale supermarket opened in 2006-07. An old order Mennonite farming area is a few miles to the northwest, whose members sell furniture, crafts, produce and gardening products.
