South entrance rotunda, Woolwich foot tunnel

The south entrance rotunda of the Woolwich foot tunnel is a structure built between 1910 and 1912, designed by Sir Maurice Fitzmaurice. It is constructed of red brick with a blue brick plinth and features a roof primarily made of lead. The rotunda is a single storey and has a canopied entrance adorned with decorative bargeboards and foliate capitals on cast-iron columns. Above the entrance, there are segmental arches over paired fifteen-pane sash windows, which are fitted with wrought-iron grilles and set in square recessed panels. A stone cornice runs beneath a panelled stone-coped parapet, and the building is topped with a conical roof that includes a circular lantern. Inside, there is a spiral staircase that provides access to the 1,655-foot-long tunnel beneath the Thames.
