Baha'i House of Worship
Just to the north of the city along the lake, and near where I live, is the Baha'i House of Worship. There are seven Baha'i houses of worship around the world, and this is the only one in North America. The building was started in 1920 and took 33 years to complete. It's now undergoing a restoration, so this was one of the only accessible viewpoints that didn't show the construction site.
