Union has a striking turn-of-the-century look architecturally, with well preserved downtown buildings and several Victorian style homes. The renowned Victorian Villa Inn, which was built in 1876, is a specimen of this architecture. In fact, it has been designated as a National Historic Landmark. An inn since 1982, the Villa provides enchanting overnight lodging, elegant yet relaxed fine dining, and the unhurried gentility of turn-of-the-century hospitality.
Union offers many antiques and specialty shops, country markets and auctions, apple orchards and winery tours, Amish settlements and horse-drawn sleigh rides, rippling trout steams and jewel green golf courses, hot air balloon rides and country craft fairs. Many of the Union house rentals and Union home rentals sit at the junction of the Coldwater and St. Joseph rivers, making the place ideal for fishing or boating.
