The “Roofless Church” in the town of New Harmony, Indiana on the Wabash River.
The actual “church” is the entire plaza-like area within the brick walls as well as an area for looking out over a field that floods each year at least once. As the foundation which maintains it says, “Johnson and [client Jane Blaffer] Owen envisioned a church where the only roof large enough to encompass a world of worshippers was the sky.”
The town of New Harmony was originally known simply as “Harmony” when it was founded by a progressive German religious group, the town changed its name when the original “Harmonists” gave the town over to yet another utopian leader.
