1. The Lock House Marker
Inscription. The Lock House is located at the southern terminus of the Susquehanna and Tidewater Canal, which operated from 1840-1897. The canal was pivotal in the development of the Lower Susquehanna River Valley. It connected with the Pennsylvania Canal at Columbia and the Conestoga Canal at Safe Harbor, opening central Pennsylvania to trade with Baltimore and Philadelphia. The Lock House built in 1840, served as the toll collector’s office and home of the lock tender.
