Seven Dials is a road junction and neighbourhood in the St Giles district of the London Borough of Camden, within the greater Covent Garden area in the West End of London. Seven streets of the Seven Dials area converge at the roughly circular central roundabout, at the centre of which is a column bearing six sundials – with the column itself acting as the seventh sundial.
