Saint Anthony's Roman Catholic Church in Hartville, Wyoming, which, if you believe the town's own Web site, is (as of 2015) "Wyoming's oldest town still in existence"! Settled in the 1870s by prospectors and a thriving city by the turn of that century, Hartville today, at population 76, "an excellent Volunteer Fire Department," in the words of that same online site, not to mention the Miners' and Stockmen's Bar -- the oldest tavern in the Cowboy State.
