John Callahan House, Annapolis

The John Callahan House is a historic brick residence built around 1785–1790 for John Callahan, a prominent government official of the late eighteenth century. Callahan served as the Register of the Western Shore Land Office from 1778 until his death in 1803 and was also a lieutenant colonel in the local militia. At that time, officials often built town houses near the main civic areas of the growing port community.

The house reflects Georgian and early Federal styles from the years after the American Revolution. It has a balanced design with a side-gabled roof and a gable-end front, an unusual feature for the time. The brickwork uses Flemish and English bond patterns, and the sash windows have 12-over-12 or 12-over-8 panes. Inside are wood details from the 1780s and a four-room layout with a stair hall in the front corner.

The building has an unusual history because it was moved more than once to prevent demolition. Around 1900–1901 it was relocated to another nearby site, and in 1972 it was moved again to its present location. At one time the house also served as the infirmary for St. John’s College before returning to residential use.
