The Crooked House or ‘Siden House’ has been a Midlands tourist attraction for well over a hundred years. The building is a typical Black Country pub, however, one side is four foot lower than the other as a result of subsidence from 19th Century coal mining. Originally built as a farmhouse in 1765, it was then known as The Glynne Arms on becoming a public house. Visitors can now experience a variety of optical illusions, including marbles rolling uphill and drinks sliding up the table, before even touching a drop!
