Winter Season view of St Malo’s Chapel on the Rock, Built atop a massive granite rock, it’s in every way a part of the valley landscape. Saint Catherine’s Stone Chapel on the Rock sits in the shadow of Mount Meeker, the 13,916-foot peak in Rocky Mountain National Park. The Chapel on the Rock (officially, Saint Catherine of Siena Chapel) is a popular tourist landmark in Allenspark, Colorado, visited by thousands every year. The chapel is located on the grounds of the Saint Malo Retreat Center, the retreat center for the Roman Catholic Archdiocese of Denver, near Mount Meeker. In 1999, Boulder County designated the chapel as a historic site. Pope John Paul II prayed at the chapel during his visit to Denver for World Youth Day in 1993.
