But at the end of this month, there's a brand new festival arriving to inject some colour into the financial district. 'Vibrance' will light up Roman ruins, medieval churches and secret gardens across the Square Mile on Thursday January 29 and Friday January 30 from 5.30pm until 8.30pm. Created by Guildhall Production Studio, it brings together more than a dozen artworks and live performances by emerging artists from Guildhall School of Music & Drama.
