Trinity Block
Why it's listed
Trinity Block is a three-story brick commercial building at 266-84 Bridge Street in downtown Springfield, Massachusetts. It was built in 1923 on the site of the Trinity Methodist Church, which had been erected in 1869 and was demolished in 1922. The new mercantile and office block cost $125,000 and was designed by the Springfield firm of Samuel M. Green Co. Its facade is notable for cast stone and brightly colored terra cotta, with color emphasizing the vertical and horizontal elements between bays. The cornice combines arches with abstracted dentils, keystones and other Classical motifs. Storefronts were rebuilt in the mid-twentieth century, though the original spacing and many transom details survive. Early tenants included the Dietz Bakery, whose successor company kept its general offices here, along with a dress shop, tea room and furrier. The building was listed for its architecture and for its role in the growth of downtown Springfield as a commercial district.
Significance in brief: The nomination argues the building is an unusual example of early twentieth century commercial design, with a colorful facade of cast stone and terra cotta. It also reflects the consolidation of downtown Springfield as a commercial area after the church it replaced was demolished. It is judged to meet criteria A and C.

What listing means for this property
For an income-producing building, listing (individually or as a contributing building in a district) is the gateway to the 20% federal rehabilitation tax credit on qualified rehabilitation costs, often stackable with state credits. Work claiming the credit must follow the Secretary of the Interior's Standards and be approved in advance.
Listing does not restrict a private owner acting without federal money or permits; where federal funding or licensing is involved, Section 106 review applies.
