The newly acquired works will go on public display when the gallery reopens.

The gallery will close to the public later this month for the works. 

‘Obelisk of Bronze’ by Michael Warren, which has been in the garden of the gallery since the 1990s, was lifted out by crane yesterday morning

All the events being held in the gallery are free, but some may be ticketed and require booking.

The gallery is expected to close for two years to facilitate renovations to the iconic building.
