This fine example of modern Gothic architecture lives up to its "Cathedral of the Rockies" name. Stained glass windows from a Philadelphia studio add a delicate grace and each window tells a different story, including many from Boise's history. Made from flagstone and sandstone, the cathedral boasts a towering spire and equally imposing cross. With a 1,000-person seating capacity and numerous public rooms, the cathedral is a popular place of worship.
