Hadrian exhibition at the British Museum

Last week, I learned the hard way that it's better to buy tickets online for the Hadrian exhibition at the British Museum. When I went over to the ticket desk, in the bottom right of the photo below, all the tickets for the day were sold out.



So, I didn't see the exhibition which I'd read so much about, and which is housed in this building in the great hall of the museum.



Next time I'm in London, I'll book ahead.
