There were plenty of displays in Cathederal square, (a lot were very noisy involving fights & guns being shot, or just the clatter of roman armour as they showed how to drill & march!
The vikings & the saxons fought each other (& charged at us too) ..with bits of shields flying all over the place when an axe or a sword hit as they tried to get at each other.
I got to see & learn about so much of our area's local history & those who lived here, there were plenty of re-enactors camped all around the cathederal & historic story telling of famous locals such as "Hereward the wake"
The actors live in their period (of the time) tents, eating & drinking the same foods that were available, we particularly liked trying the roman (spelt seed) bread, pizza & mashed up anchovies, ...so much so that dad is threatening to make some genuine roman food recipes to eat!
We learnt about roman weapons, saw plenty of armour, got to test out a roman bolt thrower (dangerous in the wrong hands) as well as, Celts, saxons, vikings, civil war cavalrymen, Napoleonic soldiers, tripod mounted machine guns from world war 1 & 2, ..in fact all-sorts, it kept us busy for most of the day!
When you realise just how many people from different parts of the world lived here you realise that being british probably means you have, Danish, Icelandic, Norwegian, French, German, Italian, Hungarian, Spanish, & African blood in our genetic ancestry, this was told very well by a lady who made us realise that the romans never left, they simply took off their armour (or tunics) & lived in Britian raising families, as did many "invaders" of the past, such as the Vikings, and Normans, right through time here where we live, including Napoleonic prisoners of war, & more recently Polish soldiers & pilots, or small children from the "kinder-transport" who fled here during world war 2 after their home countries were taken over.
You can find out lots more at the Peterborough museum (which is free to go to with parking all around it) just off Cathederal square.
(the sails were a plan by Leonardo De-Vinci ..but they were having trouble getting it to lift off the ground
it was a great example of "horrible histories" (& this one tells you a bit about our area & Hereward the wake)!
