Construction work on The Light began in 2001, as Leeds city centre experienced a vibrant year in its history.
Other highlights included Lara Croft [Tomb Raider] making an appearance on the bustling streets of Leeds, while popstar Louise Redknapp performs for crowds at Asda House.
These photos, plucked from the YEP's archive, take you back to the centre of Leeds in 2001.
