Hickory Ridge in Highland with Reip wall oven

The country home of Nicholas Greenberry Ridgely in Highland (Rt 108 between Ellicott City and Sandy Spring) was built in 1749 with an addition in the early 1800s.  It was later bought by Samuel Hopkins (nephew of Johns Hopkins) and renamed "White Hall."

Lime kilns at Marriottsville

Two kilns remain in the woods to the west of Marriottsville Road between the B&O railroad and the bridge over the Patapsco. The front wall of the one on the left had collapsed, but the 20 foot tall kiln to the right (west) is fairly intact and part of Patapsco Park.  The limestone was quarried nearby. During the colonial and federal period, lime was used with sand to make mortar and plaster, whitewash, and as a fertilizer. A lime kiln can be seen on Browns Bridge Road, Highland
