The street behind the mansions of Wethersfield Avenue

Congress Street is a single-block one-way street in Hartford. It was laid out in 1855. It served the back sides of the mansions on Wethersfield Avenue, which it parallels to the east.

The west side has Italianate two-family brick houses from the late 1850s. These were developed benefiting from the growth of the Colt Armory to the east. Granite curbs and cobblestone construction separate the paved sidewalks from the street.

The east side features larger apartment blocks dating to the turn of the 20th century. These were built as many of the estates facing Wethersfield Avenue were subdivided or redeveloped during the late 19th and early 20th centuries.

A triangular flatiron building sits at the northern end. It holds commercial establishments on the ground floor and residences on the upper floors. The district was listed on the National Register of Historic Places in 1975.
