Phoenix is located on highway 41 at the junction of M-26 to Eagle River. Once (about 1872) a thriving mining town of around 500 to 1000 people, but today there are only a few old buildings and the Phoenix Church remaining at the site of the old mine. St. Mary's Church was built in 1858 to serve the Catholic residents of the mining community of Cliff, the scene of the area's first major copper discovery in 1844. In 1899 the church was dismantled and reassembled in Phoenix, where it was renamed the Church of the Assumption. The Keweenaw County Historical Society has purchased and restored the property so the Phoenix Church appears much as it did over 100 years ago.
