312 Terry Street
Landmark Designation: 1973
National Register: 1985
Construction Date: 1892
Architectural Style: Queen
Anne
The Callahan House, constructed in 1892, is a large two and one-half story
Queen Anne style residence. The house is highly animated with steep pitched
gable bays, porches, a porte cochere and a tower porch. It sits at the north
end of a large landscaped corner site fenced on two sides by a low wrought
iron fence set in a concrete base.
Thomas M. Callahan purchased the house from the original owner, James K.
Sweeny in 1897, who moved to Pueblo to return to the milling business. During
his years in Longmont, Mr. Sweeny was manager of the Longmont Flour Mill as
well as a banker for Farmers National Bank of Longmont.
Soon after Callahan bought the house, he began to make improvements. He added
hot water heat and a four-room, two-story addition on the south rear of the
house. In 1904, the large, wrap-around front porch and porte cochere were
built and in 1908 the property was increased in size by the purchase of additional
land to the south and the expanded grounds were landscape in an "Italian"
garden theme.
Thomas M. Callahan was a prominent Longmont retail merchant and founder of
the Golden Rule Stores. Mr. Callahan along with his business partner, Guy
Johnson, expanded to a seven-state area through franchised partnerships. One
of Mr. Callahan's employees, J.C. Penney, went on to national fame. Penney
worked with Callahan from 1899 to 1907. In 1907, Penney bought out Johnson
and Callahan's interest in the Wyoming stores and established J.C. Penney
Company.
During his years in Longmont, Callahan was very active in local civic affairs
and franternal organizations. He served as an officer and/or director of several
local banks and was involved in the formation of the Arbuckle Ditch Company.
In 1938, Mr. Callahan and his wife moved to Nevada, at which time they donated
their house to the City of Longmont for exclusive use by women's groups and
clubs for meetings and special events.
Today, the Callahan House is used for various events, from business meetings
to wedding receptions. If you would like more information on the facility,
