Interdenominational services began here in 1972 under the direction of Father Walter J. Dalton, C.S.P., who offered Mass in a variety of places in Horseshoe Bay before the Chapel was built. In 1979, Wayne and Eileen Hurd donated property for a chapel and a portion of the funds to build it. The property was named Thanksgiving Mountain.

The Chapel was dedicated on December 5, 1982, and for over 10 years served the entire religious community of Horseshoe Bay. The Community of St. Paul the Apostle welcomes people from all over the country to enjoy this place of prayerful reflection. God's handiwork is visible in this beautiful natural setting.
