Built in 1900, it is one of the most flamboyant examples of wooden Romanesque Revival architecture to be found in a small-town setting in the entire state.

It is a large two-story wood-frame structure, with a hip roof, clapboard siding, and granite foundation.

The exterior is festooned with applied woodwork, with grouped round columns supporting an arcaded ground floor.

[2] Cumston Hall was completed in 1900 and is named in honor of Dr. Charles M. Cumston, a former headmaster at the English High School in Boston, who gave the Romanesque Revival and Queen Anne style building to Monmouth equipped with a library and auditorium.

Cumston chose Harry Hayman Cochrane (1860–1946), a muralist who went to school in Monmouth, to design and decorate it.
