Construction for the Neptune Pool spanned 1924-1936. Three swimming pools were built on this site, each successively larger. Initial plans for the site called for a "Temple Garden" with an ornamental pool and temple structure. On March 31, 1924, W.R. Hearst wrote in a letter to Julia Morgan, "I am sending back the plan of the temple garden with the suggestion that we make the pool longer than it is, as long as a swimming pool. Mrs. Hearst and the children are extremely anxious to have a swimming pool!" On June 17, 1924, Morgan wrote that the first swimming pool was nearing completion: "Mr. Neptune and the two ladies can be placed but the finished basins will take some time yet." The second version of the pool, a substantial enlargement, was created in 1926-1927. This version had a series of concrete steps at the southern side called the Cascade, down which water flowed. The Neptune and Nereid statues, presently in the temple pediment, then stood at the top of the Cascade. The dressing rooms were begun in 1928 and furnished according to Hearst's instruction. The present version of the pool was under construction from 1934-1936. It is unlikely that the enlargement was done to make it closer to Olympic size, as has sometimes been conjectured; Olympic pools are 165 feet long. It is more likely that the colonnades and Cassou statues, which were planned from the late 1920's, required an enlarged treatment. Morgan anticipated further modifications of the pool for Cassou's Neptune statuary group to be placed in the small upper pool. On July 27, 1936, Morgan wrote in a letter to Charles Cassou, "enclosed is a plan and some photographs of the 'Neptune Pool' in its present (uncompleted) state. The recess of the main pool and the small pool above to receive your 'Neptune' group I have not touched since my visit with you last year - so please do not think of them except as something yet to be done to form a proper background and sitting for your 'Venus' as well as your 'Neptune' statuary." The "Neptune" sculpture group by Cassou intended for the small upper pool was never installed. The final version of the pool as it stands at the Castle today is 104 feet long, 58 feet wide and 95 feet wide at alcove. It is 3.5 feet deep at the west end, 10 feet at drains and holds 345,000 gallons of water. Other unique aspects of the Neptune Pool include the oil burning heating system, the light-veined Vermont marble decorating the pools and colonnades, and four 17-century Italian bas-reliefs on the sides of the colonnades.
