Tucked smack in the middle of Portland's downtown area, this 19th-century church is a wonderful example of Venetian Gothic architecture. Speakers, concerts and of course, church services are all offered here, but the grounds and interior can be viewed weekdays. The stonework is something to see, especially the magnificent tower and checkerboard-patterned walls. The church is located near MAX light rail, Pioneer Courthouse Square and the Portland Art Museum.
