The major tour for today was the Tower of London. Like many sites in Spain, it's difficult to appreciate the immense history of the place.
The succession of British kings and occasional queen is a lot more straightforward than the Arab and Moorish conquests and the subsequent establishment and unification by the Spanish kingdoms.

The site was established by the Romans, used by William the Conqueror,and then much expanded by the Plantagenets and the Tudors. It comprises several palaces and armories. However, it's not been used as a palace for three centuries. The Crown Jewels have been on display for all of that time. It's now a marvellous museum.
The major exhibition at the moment is entitled Henry VIII: Dressed to Kill. Daniel really liked seeing all that armour.
There was a demonstration in the moat (now filled in) of siege machines used in the 13th and 14th centuries. The audience was invited to participate. Daniel, on my shoulders, was made Captain of the marauding French army and shouted "Havoc!" with great gusto. Other children volunteered to die horrible deaths as they "sacked the walls" and were repulsed by the Tower's defenders.

Two teams, men and women, operated the perrier. The men flung a pig's bladder (well, a water-filled balloon) a good distance. The women managed to drop one straight down. Much merriment was had but it emphasized the point that the machines were very dangerous.
