Kettlewell still has one of the iconic old-fashioned red phone boxes (hooray!). So many of these have disappeared from our streets, replaced by modern glass designs. But I imagine there would be an outcry if BT were to try to change this one. The National Parks Authority has very strict rules about planning and what can be changed. Ironically, when the boxes were first introduced, a lot of rural areas were upset by the bright colour. Nowadays people fight to keep these old red boxes.
The red box (K2) was originally designed by Sir Giles Gilbert Scott in 1924. He was a famous architect who designed many notable buildings including Liverpool's Anglican Cathedral. He was the grandson of Sir George Gilbert Scott who designed the Albert Memorial (see my post of June 3) and St. Pancras Station in London. The red box design was continued with minor alterations - this one is a K6, originally introduced in 1935.
