Blackrock Castle Observatory

If pirates ever try to attack Cork from the moon, this place will give ample warning. It was first built in 1582 to defend the harbour and its shipping, but twice burnt down without the help of any marauders. The present castle is a cod-medieval structure of 1828; in 2007 it became an astronomy museum and observatory.
