The Great British London Phone Box is an iconic red cast‑iron public telephone kiosk designed in 1924 by architect Sir Giles Gilbert Scott. Known for its domed roof, glazed paneled windows, and bright “Post Office Red” colour, it has become a global symbol of London and British heritage. First introduced as the K2 model and later popularised nationwide as the K6, the London Phone Box represents classic British design, civic architecture, and 20th‑century communication history.
