I found this postcard of Dr. Alfred G. Schloesser’s Castle Sans Souci in Hollywood (the Times used the addresses 1831 and 1901 Argyle Ave.) and dug into the clips for a little more information.
The castle was built about 1912 for Schloesser, who changed his name to A.G. Castles during World War I. It was designed by Dennis and Farwell, the architects of his previous home, Castle Glengarry, which was on the other side of Argyle.
In 1928, The Times reported that Castles was moving to an even more opulent home to be called Falconhurst Castle, but it’s unclear from the clips as to whether it was built.
It’s equally unclear what became of Dr. Castles, who specialized in miracle cures using glandular treatments. The last mention of him in The Times is a 1932 ad headed “Marvels of Science.”
The postcard is listed as Buy It Now for $12.99.
