This 1799 mansion is named after the lemon trees that once grew in greenhouses here in the early 19th century. The Federal-style building is notable for its stack of oval rooms and views of the city skyline.
The house was originally commissioned by Robert Morris, a major financier and signer of both the Declaration of Independence and the Constitution. In the mid-19th century, the estate was the first section of land formally acquired by the City to create Fairmount Park.
