Mount Ecclesia, Historic district in Oceanside, United States

Mount Ecclesia is the headquarters of the Rosicrucian Fellowship, set on a mesa above the San Luis Rey River Valley. Its white temple, The Ecclesia, has a central dome and smaller domes, with a cross-shaped plan and dark arched openings. The building faces east, and two palm trees stand before its columned portal.

The site was founded in 1911 when Max Heindel planted a ceremonial cross marked with the initials C.R.C., representing Christian Rose Cross. This founding act set the spiritual foundation for all future activities on the mountain.

The temple's east-facing portal carries a triangular pediment on two round columns, with an equilateral triangle and the eye of God at its centre; two palm trees stand before it. Probationers hold spiritual healing meetings there at a set time each day, a practice tied to the Fellowship's mission to heal the sick.

The site can be explored on foot, and the elevated location offers broad views of the surrounding area. Visitors should keep in mind that this is an active religious community, so certain areas may not be open to the public.

The site offers free spiritual healing services, guided by the founding principle that teachings should never cost money. This commitment to free services sets it apart from many other spiritual centers.
