Built in 1793, The Star Spangled Banner Flag House was the home of Mary Young Pickersgill and the location where she sewed the huge Star Spangled Banner flag that flew over Fort McHenry during the War of 1812.

In 2019, C&H Restoration and Renovation undertook the restoration of the exterior of the house, focusing on masonry work, window and shutter restoration, and copper flashing and downspouts.
