It was built in 1895 for Theodore Lyman, a prominent local lawyer and corporate director.

A well-preserved example of Classical Revival architecture, it was listed on the National Register of Historic Places in 1975.

[1] The Lyman House is located in Hartford's Asylum Hill neighborhood, west of downtown.

The principal alteration to the building has been the addition of a large meeting space to the rear in 1929–30.

The house is one of the few high-profile mansions to survive in Asylum Hill, a fashionable address for the city elite in the late 19th century.
