Imperial Granum-Joseph Parker Buildings, New Haven

The Imperial Granum-Joseph Parker Buildings are a pair of conjoined historic commercial buildings in downtown New Haven. Built in 1875 and 1877, the two buildings are among the finest examples of the architecture of that period in the city, with one sporting one of the city's only surviving cast iron facades. The buildings were listed on the National Register of Historic Places in 1986.

The Imperial Granum-Joseph Parker Buildings are four stories in height, and of masonry construction, with heavily bracketed projecting cornices at the roof line. The Parker Building, which stands at the corner, is built out of red brick. Its ground floor facade is a modern stylistic copy of the Imperial Granum Building. The Imperial Granum building is slightly narrower, sharing a full party wall with the Parker Building.

The Parker Building was built in 1875, and the Imperial Granum in 1877. The Parker Building was built for a paper manufacturer, who used the upper floors as a warehouse. The Imperial Granum gets is name from a patent medicine marketed by its owner, Edward Heaton, and for many years sported an advertisement of that product on its exposed southeastern wall. The buildings came under one owner in 1945, and were joined in their upper floors by breaking through the party wall, and also building a shared, interior staircase.

For many years, a hat shop named Del Monico's occupied the ground floor, so the buildings are also known historically as the Del Monico Building.
