When Yellowstone National Park was established in 1872, U.S. Army soldiers were the first caretakers of the park. Fort Yellowstone was truly a community as well as a military outpost. The small village frequently assembled to welcome new residents or bid farewell to departing neighbors. The joys of births, christenings, and marriages mingled with the sorrows of illnesses, accidents and deaths. Religious services were held in the troop mess hall, the post exchange, or in a private residence until the chapel was built.

The last of the structures built by the Army, the chapel added a “finishing touch” to the fort. Thoughtful design has given it a timeless splendor that complements its wilderness setting.

In the decades since, the chapel has continued to serve the community and parishioners. In June 2013, the chapel celebrated its 100th anniversary.
