Ste. Anne de Detroit Church, Detroit

The second oldest Catholic Church in the United States, Ste. Anne's was founded in 1701 shortly after Antoine de la Mothe Cadillac dedicated Fort Pontchartrain. The current church, located near the Ambassador Bridge, is the eighth Ste. Anne's and dates to 1886. It's a finely detailed Gothic structure with flying buttresses (unusual in the United States) and four gargoyles near the entrance. The wood altar was taken from the 1818 church. It has the oldest stained glass in Detroit, a beautifully hand-carved communion rail and an impressive old pipe organ. Mass is celebrated daily, with a second mass on Sundays in Spanish. This is one of the city's greatest architectural and historic treasures.
