Dewee's Rock

Dewee's Rock, just off of Germantown Avenue where it crosses the Wissahickon.

In 1710 a group of local men, all with German or Dutch surnames, established the Whitemarsh Reformed Church in Chestnut Hill. It met in the two-story house of mill owner William Dewees, a structure (now demolished) that stood on Germantown Avenue opposite the present Chestnut Hill College grounds. The congregation broke apart, however, following Dewees's death in 1745.

A number of mills operated in this area. Below, probably the remains of an old mill race, built to better manage the flow of water that powered the mill's wheel.
