A mansion on its own private island in Montana, US, has gone on the market for $72m (£58m).
Measuring across 45,000 sq ft, the property truly is monstrous in size and is rumoured to have its own monster that lurks beneath the surface of the surrounding water.
It's been rumoured for hundreds of years that in the water around the home lives its very own lake monster similar to Scotland's 'Nessie'
