Tonight will be the final night to catch a glimpse of Spectra – artistRyoji Ikeda’s striking pillar of light which shoots up from Victoria Tower Gardens, next door to the school, into the sky.

Commissioned by theMayor of London andWW1 Centenary Art Commissions the project was kept secret until the last minute. The beam is visible from a distance of 12 miles, unifying the city and serving as a quiet reminder of this year’s centenary.
