Arco

The Arco lamp, designed in 1962 by Achille and Pier Giacomo Castiglioni, is one of the most recognisable lighting designs in the world. Inspired by the everyday streetlight, it reimagines overhead illumination as a freestanding solution, eliminating the need for ceiling fixtures or drilled holes. Its elegant, sweeping stainless-steel arch extends light precisely over tables or seating areas, counterbalanced by a solid, parallelepipedal Carrara marble base. Every element is purposeful: the marble anchors the structure and includes a hole for easy lifting, the adjustable arch enables customizable placement, and the perforated diffuser dissipates heat. A masterclass in functional elegance, Arco embodies the Castiglioni philosophy of turning ordinary ideas into extraordinary objects. Celebrated globally, awarded copyright protection in 2011, and updated with an LED version for its 50th anniversary, Arco remains a timeless icon—uniting sculptural form, practical innovation, and a design legacy that continues to inspire.
