The Manhattan Church of Christ is a monolithic Brutalist style building on Manhattan’s Upper East Side. It was designed in 1967 by Eggers & Higgins and built on the site of a rowhouse where the congregation had previously worshiped. The firm of Eggers & Higgins was previously featured on this website here and here (one of our first entries and since demolished), which both show a similar interest in the concrete form.
The monumental stained glass window in the Dalle de Verre style was designed by Jean-Jacques Duval and features the shape of a cross (better seen when lit at night). The sanctuary is largely unadorned and is designed to enhance the acoustics of the space since the denomination incorporates a capella singing.
There are also other nice mid-century details still apparent on the inside including metal handrails and the floor tiles in the hallways.
