The Hill Military Academy, a prominent military school in Portland, moved from the northwestern district of Portland to a campus on Rocky Butte in 1931. The campus covered on the northern side of the volcano. Ran by its founder, Joseph Wood Hill, it closed in 1959 after its enrollment had declined significantly, and the school was purchased by Judson Baptist College. Today, Portland Bible College has a campus on Rocky Butte with offices and dormitory buildings, and The Grotto, a famous Catholic shrine encompassing , lies adjacent to the volcano. Created in 1924, The Grotto has more than 200,000 visitors annually. It consists of two levels, which are separated by the cliff of Rocky Butte's northern face. On the upper level of the shrine is the Chapel of St. Anne, which sits on the northern side of Rocky Butte and offers views of the Columbia River and Mount St. Helens. Built in 1934, the Chapel also has a Peace Garden (finished in 1989) and a Meditation Chapel, which was completed in 1991. The City Bible Church also maintains a location at Rocky Butte, with services on Sunday mornings at 9:30 and 11:15 am as well as youth services on Wednesdays at 7 pm. At the summit of Rocky Butte, a rotating airway beacon was erected in 1929; though the beacon is still lit, it was officially decommissioned in the late 1960s.
