Jefferson Patterson Park and Museum | Baltimore

Jefferson Patterson Park & Museum (JPPM), situated in St. Leonard, Calvert County, Maryland, spans 560 acres along the scenic Patuxent River. It stands as a unique blend of natural beauty, cultural heritage, and archaeological significance, offering an immersive experience into Maryland’s human history stretching back over 9,000 years.

Historical Background and Establishment

The park was originally a private estate donated to the state of Maryland in 1983 by Mary Marvin Patterson, in memory of her husband, Jefferson Patterson, a distinguished U.S. diplomat. The estate’s buildings, many designed in the 1930s by architect Gertrude Sawyer, showcase early 20th-century Maryland architectural styles with influences from Colonial Revival design. The grounds were carefully landscaped by prominent landscape architects Rose Greely and Cary Millholland Parker, whose work contributes to the park’s aesthetic appeal and harmony with its natural surroundings.

Archaeological Significance

JPPM is renowned primarily for its extensive archaeological resources. More than 70 documented archaeological sites within the park provide a continuous record of human activity in the Chesapeake region for over 9,000 years, from early Native American hunter-gatherers to European colonial settlers.

Excavations have uncovered artifacts and structural remains from prehistoric villages, burial sites, and colonial farms, offering vital insights into the cultural evolution of the area. The park is particularly notable for its connection to the War of 1812, specifically the Battle of St. Leonard’s Creek-the largest naval battle fought in Maryland during the war-which took place in the nearby waters of the Patuxent River.

Maryland Archaeological Conservation Laboratory (MAC Lab)

A centerpiece of JPPM’s mission is the Maryland Archaeological Conservation Laboratory, one of only three such labs in the United States. The MAC Lab preserves and curates over 10 million artifacts recovered from archaeological digs statewide. It serves as a research and education hub, where scientists conserve fragile materials and analyze finds that illuminate Maryland’s past. Although public tours of the lab have been temporarily suspended due to an ongoing expansion project, they are expected to resume, providing visitors a rare behind-the-scenes look at archaeological preservation.

Visitor Center and Exhibits

The Visitor Center, housed in a renovated former cattle barn, is the gateway for guests. It offers a wide range of exhibits detailing the history of the property, the techniques and science of archaeology, and the discoveries made at JPPM. The center includes a Discovery Room tailored for children, which encourages hands-on learning through interactive displays and activities. A small theater presents educational films, while the museum shop features books, local crafts, and educational materials.

Trails and Outdoor Exploration

Jefferson Patterson Park features an extensive trail network totaling several miles, weaving through woodlands, open meadows, and along the Patuxent River shoreline. The trails provide diverse hiking and biking opportunities, allowing visitors to enjoy birdwatching, photography, and wildlife observation. The park’s environment supports species such as deer, foxes, and a variety of birds, including migratory songbirds and waterfowl.

A canoe and kayak launch offers access to the Patuxent River, inviting paddlers to explore the waterway’s rich natural and historical environment. The park's riverfront location provides beautiful vistas and opportunities to experience Maryland’s coastal ecosystem firsthand.

Woodland Indian Village Reconstruction

In 2007, to commemorate the 400th anniversary of Captain John Smith’s exploration of Chesapeake Bay, JPPM established a recreated Woodland Indian village. This living history exhibit features four traditional wigwams, a central fire pit, and a working garden cultivated with crops typical of the era. The village offers visitors an authentic look at the daily life, culture, and survival practices of Native American communities that inhabited the region during the early 17th century.

Educational Programs and Events

JPPM hosts a variety of events throughout the year aimed at engaging the public with Maryland’s archaeological heritage and natural environment. Signature events include:

Hot for Chocolate 5K: A family-friendly race held every February to promote healthy living and community spirit.

Discovering Archaeology Day: An interactive festival offering hands-on archaeological activities, guided site tours, and expert talks designed to educate visitors of all ages about excavation techniques and findings.
