If you're wandering through some fields in the wilds of the countryside, remote and with very few buildings in sight, it's a total surprise to come across a huge ruined mansion that was once the poshest pad in the county, if not the whole of Wales.
The house is Foxhall Newydd and it's a Grade I mansion that rises up out of the ground rather randomly in the middle of a field.
Of course, if the land is private then you shouldn't actually be there, but luckily Will Millard, presenter of BBC Cymru Wales programme Hidden Wales: Last Chance to Save had permission to explore and the images of the abandoned building are breathtaking.
