This bizarre boozer makes its visitors feel a little wobbly, and not only because they've had a few pints.
The Crooked House pub in Dudley, West Midlands, has a natural leaning effect that creates several illusions - including the ability for marbles to roll uphill.
The building was built in 1765 as a farmhouse but became a pub in the 1830s, with visitors flocking to see how one side of the building is 4ft lower than the other.
The reason behind its uneven floor is subsidence due to local mining in the 1800s. Thankfully the building has been rescued and turned into a popular tourist attraction.
It was originally called 'The Siden House', meaning crooked in Black Country dialect, and drinkers from all over the world now visit the lopsided pub to check out the impressive illusions for themselves.
"The pub is mostly famous for the illusion of marbles rolling uphill and a lot of customers come to visit the crooked house, just because they've heard of the marble trick," front house manager Becks Donnelly-McHale said.
"This is caused by the level of the floor and the angles that been formed due to the subsidence of the building.
"We have regularly checks to make sure there's no further movement and damage.
"Lots of people will come because they heard from family or friends who visited before or read about it online.
"They love the quirkiness, especially if they haven't been before. They love the fact that obviously it is crooked, most of them do believe when they get here it will be just an illusion.
"They appreciate the fact that we've kept it as it was, with its original features.
"The illusion brings a lot of additional trade here at The Crooked House. A lot of people come asking about it, especially kids are particularly curious about it.
"The crooked house being as famous as it is, it brings a lot of customers from across the globe, America, Australia, Japan, China and New Zealand all year round."
