Across Maryland’s richly layered landscapes, the colonial era once lived vividly through stately manors that defined social status, architectural ingenuity, and the rhythms of plantation life. These homes, built with enduring craftsmanship, stood at the crossroads of history—hosting early governors, planters, and patriots. Yet time has slowly swept them aside. Whether through demolition, urban development, or neglect, many of these estates have lost their original form or prominence. Some are remembered only by their foundations. What follows is a look back at 15 colonial manors in Maryland whose stories echo through ruins, restorations, and the spaces where they once proudly stood.

1. Resurrection Manor (1650s, St. Mary’s County)

Once among Maryland’s earliest brick dwellings, Resurrection Manor stood as a testament to colonial craftsmanship. Constructed on a 4,000-acre land grant awarded to Thomas Cornwaleys in 1650, the manor began as a modest one-room structure with a steep garret stair, later evolving into a hall-and-parlor configuration . Despite its designation as a National Historic Landmark in 1970, the manor was demolished in 2002 to make way for private development, leading to the revocation of its landmark status in 2006 . Today, Resurrection Manor exists only in photographs and historical records, its physical presence erased, leaving behind a poignant reminder of the fragility of our architectural heritage.​

2. Whitehall (1764, Annapolis)

Erected in 1764 for Horatio Sharpe, Maryland’s last colonial governor, Whitehall exemplified Palladian architecture with its five-part Georgian design and rare temple portico . Situated on a 1,000-acre estate along the Chesapeake Bay, the manor was adorned with intricate woodwork by William Buckland . However, over time, Whitehall’s prominence faded. While the structure still stands, its historical significance has been overshadowed by modern developments and changing landscapes. The once-grand estate now serves as a silent witness to a bygone era, its stories largely forgotten by the public.​

3. Oakland Manor (1810, Howard County)

Once a symbol of Maryland’s plantation economy, Oakland Manor was established in 1810 by Charles Sterrett Ridgely on land originally patented as “Dorsey’s Adventure” in 1688. The manor evolved into a significant agricultural estate, later owned by George Riggs Gaither, a Confederate sympathizer during the Civil War. Despite its storied past, the manor’s prominence has faded. Modern developments have encroached upon its once vast lands, and its historical significance is often overlooked. The echoes of its past, from colonial beginnings to Civil War affiliations, are now faint whispers amidst the suburban landscape. ​

4. Wye House (1784, Talbot County)

Constructed between 1784 and 1790 by Edward Lloyd IV, Wye House was the centerpiece of a vast plantation that, at its peak, encompassed over 42,000 acres and enslaved more than 1,000 individuals. The estate is notably associated with Frederick Douglass, who spent part of his early life there. The plantation’s infrastructure, including slave quarters and work buildings, have vanished. This physical erasure contributes to a diminished public awareness of the site’s full historical context, leaving behind a fragmented narrative of its complex past. ​

5. Old Parish House (1817, College Park)

Erected in 1817 as a dairy barn for the Calvert family’s Riversdale estate, the Old Parish House once stood as a testament to the region’s agrarian roots. Over the years, it transitioned from a barn to a parish hall, reflecting the evolving needs of the community . Despite its historical significance, the building’s original purpose and prominence have faded from collective memory. Modern developments and changing urban landscapes have overshadowed its past, leaving behind a structure that, while still standing, is often overlooked in the narrative of Maryland’s colonial history.​

6. Williams Plains (1812, Bowie)

Constructed in 1812 for Judge John Johnson, Williams Plains once epitomized the architectural elegance of early 19th-century Maryland. Its Greek Revival interior and Flemish bond brickwork showcased the craftsmanship of the era . However, as time progressed, the manor’s significance diminished.

Modern developments and changing land use patterns led to its gradual obscurity. Today, Oakwood is largely forgotten, its legacy overshadowed by the march of progress and the fading memories of Maryland’s colonial past.​

8. Perry Hall Mansion (Late 1700s, Baltimore County)

Established in the late 1700s, Perry Hall Mansion was once the centerpiece of a vast plantation northeast of Baltimore.

The mansion’s historical significance has been largely overshadowed, its stories and grandeur fading into the background of modern developments.​

9. Carrollton Manor (1700s, Frederick County)

Granted to Charles Carroll of Carrollton, Carrollton Manor once spanned 17,000 acres between major rivers and mountains. It stood as a showcase of wealth and power in colonial Maryland.

Oxon Hill Manor, constructed in 1929, stands on land that was once home to the Addison family’s colonial plantation.
