1. Seneca Marker
Inscription. Eleven aqueducts were built from Georgetown to Cumberland to carry water over water. The aqueducts, literally “water bridges,” carried the canal over large streams and rivers flowing into the Potomac River. This aqueduct enters directly into the lock, the only one on the canal to do so.

The Seneca Creek Aqueduct, or Aqueduct Number One, Lock 24, and the lockhouse were built of Seneca Red Stone quarried nearby. This same distinctive sandstone was used to construct the Smithsonian Castle on the Washington Mall.

(Inscription next to the image on the top right)
The Riley name is forever linked to Lock 24. The Riley family (right) lived in the lockhouse for many years. After John Riley (on left in photo) died, Mrs. Riley took over duties as lockkeeper and had over 45 years of service here.
