Fortnum & Mason's Christmas windows for 2025, window by window: unicorns under disco balls, narwhals, a Highland cow, a parrot, and the mice in red coats. What was in them and when to look.

Fortnum & Mason has been trading on Piccadilly since 1707. You can walk in off the street with no appointment, wander several floors of food hall and leave having spent nothing at all, and plenty of people do. Here is what to look at while you are there: the chocolate counter, the spiral staircase, the Duke Street stairs and the four-tonne clock on the shop front.
