Mount Angel Abbey
Fodor's choice
This Benedictine monastery on a 300-foot-high butte was founded in 1882 and is the site of one of two modernist buildings in the United States designed by Finnish architect Alvar Aalto. A masterpiece of serene and thoughtful design, Aalto's library opened its doors in 1970, and has become a place of pilgrimage for students and aficionados of modern architecture. You also can sample beers produced by the abbey's in-house brewery (the aptly named Benedictine Brewery) at its taproom just up the road.
