The Grange Estate, also known as Maen-Coch and Clifton Hall, is a historic mansion built by Henry Lewis Jr. (1671–1730) in Havertown, Pennsylvania, near Philadelphia.

The land was purchased by Captain John Wilcox in 1750, and quickly sold to Charles Cruikshank in 1761.

The mansion, an example of the Gothic Revival style,[3] is presented in the state it was in at the turn of the 20th century.

[4][5] The house was owned by patriot and Philadelphia merchant John Ross during the late 18th century, who named his country estate after the home of Lafayette.

Ross's house was frequented by several notable historic figures, including George Washington and Lafayette.
