Another work of art in the public spaces of Trinity College, Dublin. This large metal sculpture is ‘Cactus Provisoire’, created in 1967 by Alexander Calder. Best known for his “kinetic sculptures”, this is one of his non-mobile “stabiles”
It’s located in Fellow’s square, an open space between the college library used by students and the old library which houses the Book of Kells. The square is on the well traversed route through the college between College Green and Nassau Street. So plenty of people pass this sculpture every day.
