The unveiling of a bigger, better Tate Modern marks a “landmark moment”, said Lord Browne, chairman of Tate Trustees, at the recent press launch of the gallery’s new extension. “At a time when some would seek to turn inwards, the new Tate Modern is a reminder of what can be achieved when we remain open to the world’s ideas and cultures.”

No prizes for guessing where he stood on the EU Referendum. At a volatile moment in British national politics, Tate Modern has rebranded itself as a museum of global contemporary art. The 60 per cent of additional space opened up by Herzog and de Meuron’s beautifully airy new Switch House extension houses work by 300 artists from more than 50 countries.

The new displays in both the Switch House and the old power station building, renamed the Boiler House, have dramatically tilted the balance away from the household names of the Western art canon towards lesser-known artists from developing economies.
