Lexington Park History

As part of Saint Mary’s County, Lexington Park has a long and illustrious history. The area housed some of Maryland’s first settlements and was the primary stomping ground of George Calvert, the nobleman who is widely regarded as Maryland’s founding father. During its early history, the Lexington Park area featured sprawling tobacco plantations and a thriving crabbing industry. Although it escaped the worst carnage of the Revolutionary and Civil Wars, its economy remained somewhat languid until the early 20th century. These days, it continues to respect its storied history while working hard to attract vacationers and second-homeowners.


Lexington Park is located on Maryland’s Eastern Shore, a largely rural region that abuts the Chesapeake Bay. The town’s built-up area consists of 19th-century dwellings as well as newer residential and commercial subdivisions. It’s close to a number of other rapidly growing settlements, including Great Mills and Hollywood. The land that surrounds Lexington Park is characterized by a flat or gently rolling patchwork of dairy farms, tobacco fields and hickory forests. The wide Patuxent River marks the town’s northeastern boundary. Local thoroughfares include Maryland Highways 235 and 246.

Population and Demographics

According to the most recent Census figures, Lexington Park has a year-round population of around 12,000. Although the town itself isn’t particularly large, it’s adjacent to several decent-sized settlements that collectively house over 50,000 individuals. Many locals can trace their heritage back for over a century, but the Lexington Park area is home to a fair number of retirees and second-homeowners as well. While its economy remains tied to agriculture and the maritime trades, enterprising young people are flocking to the area in search of opportunities in the tourism and technology industries.

Things to Do in Lexington Park, Maryland

Lexington Park has a host of family-friendly attractions. The nearby Patuxent Naval Air Station is home to the Patuxent River Naval Air Museum, an open-to-the-public collection of artifacts from early aviation history. Meanwhile, Mattapany-Sewall Archaeological Site wows visitors with remnants of a prehistoric settlement. Nearby St. Richard’s Manor contains well-preserved structures and top-notch artifacts that recreate the life of the area’s early colonists. For folks who wish to stretch their legs, St. Mary’s River State Park boasts an impressive network of hiking trails. To the south, Chancellors Point Natural History Area features one of the largest estuaries on the Eastern Shore.

Climate and Weather

Like the rest of the Eastern Shore region, Lexington Park has a subtropical climate that’s heavily influenced by the proximity of the Atlantic Ocean. During the transitional seasons, continental air masses clash with oceanic moisture to produce dense fogs that give the region a spectral atmosphere. In the winter, chilly and damp conditions prevail. Although snow and sleet aren’t exceedingly rare, most winter precipitation comes in the form of cold rain. During the summer, hot and humid weather settles on the region. Frequent thunderstorms provide relief from the mugginess.
