It served as a stagecoach stop along the National Pike road. The hotel was later called Stewart's Hotel featuring a bar and bowling alley. In 1806, Chief Little Turtle of the Miami people, Chief of the Rusheville people, Beaver Crow of the Delawares, Chiefs of the Shawanese, and the chief Raven of the Potowatomies visited George Ellicott staying at his home and the Hotel while returning from a visit to Washington, D.C. The second floor balcony led to and served as an unloading terminal for the B&O Railroad at Ellicott's Mills. Henry Clay once performed a speech from the balcony during a presidential campaign. During the civil war, the hotel was considered a host of Southern Sedition. The hotel operated as late as 1879. For a period the hotel was used for an ice house for a period. In 1920, the hotel owned by Hezekiah I Thomas was not in use with the windows broken and the county condemned the property. In 1926, a wall adjacent to the railroad collapsed, causing streetcar service to be halted. Passenger cars had to halt as an inspector checked for enlargement of cracks before they could pass the building.

The original foundation was used, including some standing walls. The building was converted into an apartment house in the 1940s.
