Shafer Historical Museum
The museum is made up of several downtown buildings that nod to Winthrop's colorful mining and ranching past, including "the castle," a late-19th-century log house built by one of the town's pioneer founders. Other structures include a country store, print shop, schoolhouse, women's dress shop, and an open-air display of vintage mining equipment. Although you can go inside the buildings in summer only, the grounds alone are worth a stroll and are open year-round.
