Kim Hampton correctly identified the picture as a shot of the sanctuary of Unity Temple Unitarian Universalist Congregation, in Oak Park (just west of Chicago proper). This famous site was designed by Frank Lloyd Wright, himself a member of the congregation from a prominent Unitarian family that included the influential minister Jenkin Lloyd Jones. Unity Temple was a combined Universalist and Unitarian congregation well before the denominations merged, and in designing the building Jones wanted it to express UU principles. The sanctuary is particularly noteworthy: while it seats over 300, it’s wrap-around design means that no one is ever seated more than 45 feet away from the pulpit, making it an intimate, all-embracing space that doesn’t radically separate members from one another or from the minister.
Below are a few more photos for you to enjoy. First, an angled shot from the pulpit showing a bit of the wrapped tier design of the seating. Second, a shot of the many skylights overhead of the sanctuary. Finally, a picture of the outside of the church.
