Third Church of Christ, Scientist, established in 1918, is a Christian Science church in downtown Washington, D.C. From 1971–2014, the church was located in a controversial building at 16th and I Street NW. Considered a significant work of "Brutalist" church architecture by some critics, the building was considered unsatisfactory by members of the Church's congregation, which shrank over the years. In 2007, the church applied for a demolition permit for the building to permit sale and redevelopment of the site, with plans to relocate to a more suitable structure. A 1991 application for landmark status for the building, filed to forestall a demolition threat then, was subsequently approved.
