> Picc-Vic: Arndale Void 📍
This is the spot of an apparent void in the depths of the Arndale, purportedly reserved for the entrance to or the main area of the Royal Exchange Picc-Vic station.Next time you pass Topshop, pause to contemplate the fact that 30ft below it is an enormous hole which was almost certainly dug to be part of a swanky Manchester tube system.
