Cathedral of Saint John Gualbert

The Cathedral of Saint John Gualbert is a Renaissance Revival church in downtown Johnstown with a prominent bell tower rising above Clinton Street. The building features classical proportions and a striking interior, with a structural system based on steel rather than traditional masonry bearing walls.

The cathedral was completed in 1895 as a pioneering example of innovative construction using a steel framework. It gained greater importance when designated as a co-cathedral of the Diocese of Altoona-Johnstown in 1957.

The cathedral displays four large bronze doors depicting scenes from Saint John Gualbert's life, connecting visitors to the reverence for this saint. The pipe organ donated by Andrew Carnegie remains central to services and shapes the sonic character of worship here.

The cathedral is open daily for visitors and welcomes people during its regular religious services. It is best to check opening times ahead of your visit and be respectful of any ongoing prayers or ceremonies taking place inside.

This was the first church in the world built with a complete steel superstructure as its primary support system, well ahead of its time. This engineering achievement made the building a pioneering example of how new construction methods could transform religious architecture.
