Described in "50 Rooms With a View" published in the Los Altos Town Crier:

"With its curving blue tile roofs Maryknoll Residence is the jewel of Highway 280, located in Santa Clara County with a Los Altos address. Set on 35 acres of rolling hills, it is home to retired Maryknoll priests and brothers, a beautiful and distinctive local landmark since 1926. Originally built as a seminary to train priests for missionary service, it now provides a bucolic haven for missioners who have completed their careers."

...

"An architectural mix of Mission/Asian/Baroque and Romanesque styles, the building's towers and wings, connected by outdoor arcades and indoor corridors, create a mini-village with strong flavors of Spain, Italy and the Orient. Re-designed in 1976 as a retirement home, today the structure's beige-pink stucco walls, variegated terra cotta floors and handsome interior woodwork is beautifully maintained and preserved.

Outdoors, the trees, paths and gardens reflect more than seven decades of careful grooming and renewal. Spring 2000 bursts forth with magenta bougainvillea, climbing rosebuds and colorful flower beds of pansies, primroses and canna lilies."
