House at 491 Prospect Street

The House at 491 Prospect Street in Methuen, Massachusetts is locally significant as an excellent example of a Shingle Style house of the type built for well-to-do businessmen in Methuen and Lawrence around the turn of the 20th century. The three-story wood-frame building was built c. 1900. One of its principal decorative features at the time of its listing on the National Register of Historic Places in 1984 was a Palladian window in the gable, around which square-cut shingles had been arranged in a keystone motif. This detail has since been lost due to the application of new siding.

Other details of note include curved exterior corners, a window recessed in a bay with curved walls, and small decorative rectangular and oval windows. The property also includes a period carriage house.
