Henry Moore’s “Vertebrae 1968” – Sculptural Highlight

The piece consists of three interlocking elements reminiscent of bones or flints, adding a thoughtful artistic presence to the plaza.
- Commissioned and installed outside the building upon its completion
- Cast in an edition of four; copies are displayed in Jerusalem, Münster, and at Moore’s foundation in Perry Green, Hertfordshire
