If you want a cool industrial-chic wedding with the elegant touches of a luxury venue, consider the Titanic Hotel in Liverpool's Stanley Docks. Styled like a Manhattan loft, housed in a Grade-II listed warehouse, it can host a huge 600 guests in its Rum Warehouse.
With floor-to-ceiling iron windows and brick walls, you'll love having cocktails overlooking the water. The really cool bit? There's a replica of the sunken liner's grand staircase, perfect for your own Kate and Leo moment.
