A 12th-century Irish castle is on sale for about $2.2 million, the same price as some NY apartments. Blackwater Castle has nine bedrooms, a holy well, and access to a private river.

This one-bedroom miniature castle in Dover, Kent comes with its own tiny turret and gothic interior and is hitting the market for a decidedly un-princely sum.

An unearthed photograph from before the royal couple lived at the $29 million property, revealed on YouTube, shows a little girl's room decked out with a giant castle bed.
