Saint Aloysius Parish Church

The Washington Boulevard Historic District is significant as an intact streetscape of architecturally distinguished commercial buildings dating from 1901-1930 with a majority built in the 1920s. The buildings individually represent some of the finest early Twentieth Century architecture in Detroit and as a group illustrate the evolution of the commercial style in Detroit as it was practiced by some of Michigan's master architects. The district is also significant as a product of a planned real estate development inspired by the City Beautiful movement and carried out as the private artistic endeavor of one family and their architect, Louis Kamper.

In 1930, Donaldson & Meier designed a new church for St. Aloysius adjacent to the Chancery Building. Since the church is abutted on both sides by buildings, it only has one elevation. This facade is a limestone, Italian Romanesque basilican composition ornamented with extensive Romanesque carving, grouped pilasters, arcaded corbeling, open arcading, a rose window and carved, arched, door surrounds.
