The Church of The Blessed Sacrament at 1 Commonwealth Drive opened in 1965 by Archbishop Michael Olcomendy, Iversen & Van Sitteren Partners as the Architects. In 2005, the Urban Redevelopment Authority of Singapore (URA) designated the church as a conservation site. Its folded roof structure, a distinctive feature of its interior, imparts a transcendent spatial quality. The church underwent restoration, including its interiors, from 2021 to 2023.
