Arco Floor Lamp was designed by Achille Castiglioni in 1962.
 

--Inspired by the design of a streetlight, the Castiglioni brothers��?dramatic steel and marble Arco Floor Lamp provides overhead lighting without requiring ceiling suspension.

--Supported by a weighty marble base, the Lamp's polished stainless steel shade extends eight feet into a space, leaving room for a dining table or sofa to be positioned underneath the light source.

--To make the Lamp easier to carry and move, the designers placed a hole in the base that accommodates a broom handle. The edges of the marble block are beveled, which might appear to be decorative, but the real reason the brothers removed the block's sharp corners was for safety.
