The Roman Pool at Hearst castle is a tiled indoor pool decorated with eight statues of Roman gods, goddesses and heroes. The pool appears to be styled after an ancient Roman bath such as the Baths of Caracalla in Rome c. 211-17 CE. The mosaic tiled patterns were inspired by mosaics found in the 5th Century Mausoleum of Galla Placidia in Ravenna, Italy. They are also representative of traditional marine monster themes that can be found in ancient Roman baths. The statues are rough copies of ancient Greek and Roman statues. One such copy represents the “Apoxyomenos.” Statuary was used on a considerable scale in the Baths of Caracalla.

The pool and surrounding room, which were built from 1927-1934, can be compared to an ancient Roman bath. It is decorated from ceiling to floor with 1″ square mosaic tiles. These glass tiles, called smalti, are either colored (mainly blue or orange) or are clear with fused gold inside. The intense colors and shimmering gold of the tiles combine to create a breathtaking effect. [Source]

Hearst Castle is a National and California Historical Landmark mansion located on the Central Coast of California, United States. It was designed by architect Julia Morgan between 1919 and 1947 for newspaper magnate William Randolph Hearst, who died in 1951. In 1957, the Hearst Corporation donated the property to the state of California. Since that time it has been maintained as a state historic park where the estate, and its considerable collection of art and antiques, is open for public tours. Despite its location far from any urban center, the site attracts about one million visitors per year. [Source]
