The Rest (Lyles-Magruder House): Also known as the Lyles-Magruder House, this estate is the oldest extant building in Tenleytown.

The Rest, also known as the Lyles-Magruder House, was once a part of Mrs. Magruder’s great estate. The Tenleytown residence has incredible historical significance over three centuries, as it held many of the Washington family's heirlooms, was used as a stop on the Underground Railroad, and was a prime location for gambling and drinking during the Prohibition Era.

The house still holds much of its original integrity, showcasing original windows, heavy hand-hewn timbers in its floors and basement, old iron locks and bolts still in good working condition, a few historic marble mantle-pieces, and a narrow, winding staircase, all typical of estates built in the early 19th century.

The location that the estate was built upon was originally a log hut, with construction that dated to 1700, but it was later converted into a family mansion upon coming into the possession of the Lyles family. The estate is the oldest extant building in Tenleytown. The last family member to own the house was Eleanor Magruder, who still held many family heirlooms when she died in 1905.

The Rest remains a residence and recently underwent a restoration.
