Havre de Grace in Harford County, Maryland — The American Northeast (Mid-Atlantic)
Adding On
Several outbuildings were added to the property after the initial construction of the Keepers House.
A well was dug in 1827 and research indicated that a pump was installed to draw water.
The pump house was added over the well in 1851. This building provided some shelter from inclement weather and a convenient location next to the Keepers House. There was one small window located on the North elevation to provide light.
A coal shed was built at the same time as the pump house. The shed was attached to the West wall of the building and was of equal length. From the few images that exist, it appears that the coal shed was a rudimentary structure used only for storing fuel in the winter.

Any changes to the property had to be submitted to the United States Lighthouse Establishment for approval. Orders were also placed for the materials necessary to make these changes. Lighthouse Accounts from September 30, 1851 shows an order placed for items on the list to the left. These supplies were likely used to build the pump house and coal shed.
