1. Did you Know? Marker
Prior to the building of the Conowingo Dam in 1928, this area flooded every spring when the snow melted. Light keepers used a boat to go from the house to the lighthouse in order to light the lamps.
Raised wooden walkways were constructed between 1884 and 1890 to reach the outbuildings, including a privy located on the west side of the property. The first privy, built in 1827, included these building instructions, "Also an outhouse or privy at a convenient distance from the dwelling of stone or brick five feet by five feet in the clear, with a well at least eight feet deep, walled up with stone or brick; the roof to be well shingled."
