Copenhagen’s Grundtvig’s Church is a rare example of expressionist church architecture, and one of the most well-known churches in the Danish city. French photographer Ludwig Favre was attracted to the perpendicular lines that compose the early 20th-century structure, in addition to the nearly six million yellow bricks that fill its interior. Favre decided to shoot the building’s 1800-seat congregation, capturing the minimal ornamentation found in the famous church’s massive vaulted halls and nave.
