The tunnel is 370m long and the footpath has an internal width of 3.2m and height of 2.65m. The floor is made of stone paving and the internal walls are covered with glazed tiles. The subterranean link is used by 1.2million people a year and the listed building¹ has become an interesting London landmark because of its unusual and interesting acoustic characteristics.
