Rackliffe House, Colonial house museum in Berlin, Maryland.

Rackliffe House is a colonial brick residence in Berlin, Maryland, situated near a coastal bay. The structure displays three bays with characteristic Flemish bond construction and steep gable roofs, while large windows face the water.

In 1679 a grant of 2,200 acres called Genezeer went to Charles Rackliffe and Edward Wale, the oldest colonial property in northern Worcester County. Around 1752 Captain Charles Rackliffe built the 38-by-32-foot double-pile brick house. A 1790 inventory listed 10 slaves, 220 cattle and 28,000 pounds of tobacco. A 1929 fire gutted it; Maryland bought the house and 114 acres in 1996.

The house is named for Captain Charles Rackliffe, who built it around 1752 on a 1679 land grant originally called Genezeer. Enslaved African Americans on the plantation raised tobacco, corn and wheat; a 1790 inventory listed 10 slaves and 28,000 pounds of tobacco. The Rackliffe House Trust, founded in 2004 by descendant Tom Patton, now runs the site as a Coastal Maryland Heritage Center.

This house museum operates through state park administration and offers guided tours during warmer months to protect the building. The grounds remain accessible from sunrise to sunset, allowing visitors flexibility to explore the property at their own pace.

A 2010 dig led by archaeologists Aaron Levinthal and Ryun Papson sank 300 small test holes and found pieces of pre-1650 Native American pottery, a possible dumping ground in a swampy area and a buried brick walkway. More than 40 volunteers took part, and three-quarters of the property's soils remain undisturbed.
