Lagoon by Sir Anthony Caro (1976/7)

Standing just over two metres high on the forecourt of the Key Theatre, Lagoon is an inviting piece of modern British sculpture by Sir Anthony Caro, one of the country’s most influential post-war artists. Made from interlocking sheets of mild steel, bolted and welded together, the sculpture creates shifting patterns of shape, light, and shadow as you walk around it. Caro placed his works directly on the ground, removing the barrier of a plinth so visitors could experience them up close from every angle. Here, the weathering steel adds its own patina over time, making the piece feel alive to the changing seasons along the Embankment.
