17:30 PM Evensong at the extraordinary King’s College Chapel should be on every visitor’s list. Nowhere in the city comes close for atmosphere or bewildering historical building-craft as this. It is unquestionably one of the finest examples of Gothic architecture in the UK. But if impressive on the outside, it is even more spectacular within: sixteenth-century stained glass windows tower upwards to an 80m-long, fan-vaulted ceiling (the world’s largest), jewelled with astounding stonework. Begun by Henry VI, the chapel wasn’t finished until nearly a hundred years later by Henry VIII, but it remains a fitting stage for its world-famous choir, which sounds especially evocative around Christmas or during the enchanting, calming, candlelit service known as evensong. To experience the latter, arrive at 5pm and queue outside the college gates. Services are free, last 45-minutes and are held at 5.30pm from Monday to Saturday, and at 10.30am and 3.30pm on Sunday.
