The prominent Spanish Renaissance-style Cathedral Tower was designed by the Bryan family and the architect Clarence L. Jay, and has been a landmark since its construction in 1924–1925.

There are elaborately designed doorways and arches, large Spanish windows in art glass, imported marbles, and tiling.

Long Beach resident Frank Julious Fisher[2] created the intricate stencils and woodcarvings tracing the walls of the mausoleum.

The Memorial Chapel, in adobe and red tile architecture, also reflects early California's Spanish and Mexican lineage.

Beyond the stained glass window there is a carved reredos leading toward the mural interpretation of The Ascension of Christ, created by R. Brownell McGrew.
