Anyone currently scouting for a new career would be well advised to head to Spain. For there, on a hilltop 40 miles north of Madrid, if you play your cards right, you might just talk yourself into the cushiest job in the world: staffing a completely empty house.

There are qualifiers. The house isn’t just a house; it is basically a castle. Nor is it simply empty; despite being fully staffed and patrolled by security to the tune of an alleged $515,000 per year, the house has never even had a visit from its owner. More than that, according to the Daily Mail, he doesn’t actually know where it is. More than that, the house—with its decades-old kitchen appliances still wrapped in the cellophane they came delivered in—has only ever been visited once, by the owner’s son, 17 years ago. And he left without staying the night.
