The Swiss Light at Tate Modern lit up at night, 2000

Swiss Light 1999 was a temporary enhancement to Tate Modern’s chimney and symbolised the birth of the gallery and the reincarnation of Bankside.

Michael Craig-Martin, artist and former Tate Trustee, collaborated with architects Herzog & de Meuron to develop the chimney design.

The resulting creation was a lightweight luminous roof, fabricated from translucent panels, which illuminated the chimney’s apex like a beacon. Artist and architect together produced a crowning gesture to define the major architectural and cultural achievement of Tate Modern.

The light incurred some damage during exceptionally high winds and was dismantled in 2008. Swiss Light 1999 has been supported by the Swiss government.
