Ok, so it's not really a castle but this is still a cool looking house.
2881 Rumsey Dr in Riverside is in the Victoria Woods area just south of Victoria Ave. This house was built in 1926 and from the few pictures it's a very cool property. I really wish they had included more than 7 pictures. The estate is covers nearly an acre and the home is just under 5000 sq/ft. It last sold in 2006 for $1,475M. It's currently listed as an REO for $550K. If my math is right that's about 63% off the bubble price. It's currently listed for less than it sold for in 1998!
Nice stained glass and check out that ceiling!
More details, check out the doors. And look at the detail in that ceiling.
