Pierce-Klingle Mansion

Pierce-Klingle Mansion is a three-story building with ten rooms constructed from blue and grey granite with walls 24 inches (61 centimeters) thick. The structure currently houses administrative offices and is not open to visitors.

Joshua Pierce built the mansion in 1823 and named it after Swedish botanist Carl Linnaeus. Pierce later became a supplier of ornamental plants to the White House, establishing a connection to the nation's highest office.

The mansion served as a gathering place for prominent political figures during the nation's early years. This social significance shaped how people viewed the property as a center of influence in Washington's developing society.

The building sits within Rock Creek Park and can be reached via nearby parking facilities, but the interior is not open for tours. The exterior and surroundings can be viewed from park pathways when exploring the area.

The property includes a two-story stone and wood barn with entrances designed to match different ground levels on the site. This design solution shows how early builders creatively adapted to the terrain.
