The Grotto Meditation Chapel, built in 1991 to honor the memory of Marilyn Moyer, rises from the north face of Rocky Butte; it provides a panoramic vista of the Columbia River and Mt. St. Helens. On a clear day even Mt. Rainier may be visible. The Meditation Chapel is 1,500 square feet in size, built of polished granite.
The cliff-side glass exterior of the Meditation Chapel with its lighted cross offers a dramatic view which can be seen by southbound travelers on Interstate 205. The building has received both national and international architectural awards.
