The Hotel Del Monte was a large resort hotel in Monterey, California, from its opening in 1880 until 1942. It was one of the finest luxury hotels in North America. During World War II, it closed and the building was leased to the United States Navy. It first was used by the Navy as a school where enlisted men spent the second, third, and fourth months of an 11-month course being trained as electronic technicians. Later the Hotel Del Monte became the Naval Postgraduate School.
