The much-imitated Arco Lamp was first created by brothers Achille Castiglioni and Pier Giacomo in 1962, and continues to be a beloved design to this day.

Functioning as a freestanding piece of furniture rather than a background light fitting, a stainless steel arch sits above a stylish White Carrara marble base, extending over a table or chair, and offering a more flexible standalone solution to lighting. A new lamp costs £2,397 ($3,152), while a vintage Arco lamp costs on average £2,889 ($3,799).
