Lock 22, aka Pennyfield Lock, was built between 1829 and 1831, and the name came from the misspelling of the Pennifield family name. It has been restored and offers overnight stays to recreate the rustic feeling from that period.

Built in 1837 by the Seneca Sandstone Company, this mill was created to process the distinctive red sandstone quarried nearby. Today, the ruins, easily spotted by their red sandstone walls, are accessible via the C&O Canal towpath and are especially visible during the winter months when vegetation is dormant.

Historic ferry crossing over the Potomac along the C&O canal bike trail. Donald Trump's golf course is not far away on the Virginia side and I saw him once across the river while biking on the trail in July 2020.
