A hilltop castle in San Antonio has been on the market for more than half a year - 188 days, to be exact - and it's still waiting for its white knight.

Sitting on two acres near the Dominion, this keep is fit for a king, but so is the price tag, which stands at $4. 3 million.

Though the house was built in 2007, its design evokes the age of King Arthur and the Knights of the Round Table.
