OF THE ESSENCE
The pared down, polished sculptures of Constantin Brancusi are the subject of a new exhibition at Tate Modern, which opens today and continues until 23 May.

The Tate is open daily.There's more Brancusi at Kettle's Yard, Cambridge, until 14 March.
Information for inclusion should be sent to Andrew Mead at The Architects' Journal at least two weeks before publication.
