Giuseppe Penone at Museum Voorlinden (until Jan 29) is a large retrospective of land art and ‘arte povera’ – literally, poor art, a radical Italian movement of the 1960s and ‘70s which explored unconventional processes and non-traditional, everyday materials. Penone’ s works in the exhibition range from iconic sculptures and immersive installations to more modest, intimate pieces. Every Saturday and Sunday morning between 10am and 11am is ‘Silence on socks’ hour, when you can store your shoes and experience the works in tranquility.
