The George F. Tyler Mansion (1928–31), also known as "Indian Council Rock," is a French-Norman country house and former estate which is located in Newtown Township, Bucks County, Pennsylvania.

Seventeen year later, George married his stepmother's niece, Stella Elkins (1884–1963), a budding sculptor who later studied under Boris Blai.

They decided to build a country house on the east bank, and by a decade later had assembled a property of nearly 2,000 acres (810 ha), about 3 square miles.

The resulting estate was named for one of its landmarks, "Indian Council Rock," a cliff overlooking the creek, that was reputed to have been a meeting place for the Lenni Lenape tribe.

Now known as "Tyler Hall," the mansion – still surrounded by formal gardens, stone walls and fountains – houses the college's administrative offices.
