The Cathedral of Saint Paul is a large Beaux-Arts church completed in 1915, sitting on a prominence at the top of Summit Avenue. The building is modelled loosely on St. Peter's in Rome — a wide nave, an elaborate sanctuary, and a dome that is visible from much of downtown St. Paul. The interior is cooler and quieter than its exterior suggests, with high windows that filter the Minnesota light.
The cathedral is an active parish and open to visitors during the day. It anchors the east end of Summit Avenue, providing a starting point for the walk west along the mansions toward the Mississippi. Free tours are available on most weekdays.
