Pompeii should not just be a day-time experience So congratulations to the British Museum, but in the light this success, we make a plea - to extend the opening hours. They are currently 10am until 5.30pm, with the sole exception of Fridays, when visits are possible up till 8.30pm. Shouldn't it be 8.30 every evening? The public demand is there. Surely so triumphant an institution can organise itself to meet it?
