Abandoned church in St. Marie, Montana on the Glasgow AFB

Across military bases worldwide, Roman Catholic chapels have long served as sacred spaces of comfort, continuity, and community. These churches aren’t just places of worship—they’re deeply woven into the lives of service members and their families, offering spiritual support through the highs and lows of military life.

Catholic churches on bases often reflect the architectural style and era of the installation, ranging from simple chapels to grand, purpose-built sanctuaries. Inside, you’ll find familiar traditions like mass, confession, sacraments. Military chaplains, often active-duty priests themselves, provide pastoral care tailored to the unique stresses of deployment, separation, and uncertainty.

During times of war and peace alike, these chapels have hosted everything from Sunday services to weddings, baptisms, and memorials. For many, they are a reminder of home, identity, and stability amid the transient and high-stakes environment of military service.

Today, as bases modernize or close, the churches are left behind. Many of the ones on Canadian bases are built from the same plan and easy to spot. This one in Montana has a different design but the same features on the inside. It has been abandoned for years but was very much a time capsule, like they held a service the Sunday before. Everything was in its place with no vandalism at the time of our exploration.
