St John Gualbert Cathedral is one of downtown Johnstown's most distinctive landmarks, its twin towers rising above the compact street grid. The church reflects the city's immigrant Catholic history and gives the centre a piece of architecture that is both religious and civic in feel.
Step inside if the doors are open. The interior is more elaborate than the outside suggests, with stained glass, carved detail, and a scale that feels ambitious for a post-industrial Pennsylvania city. It is a short visit, but a worthwhile one while walking between Johnstown's museums and flood-history sites.
