The children learnt about castles from 1000 years ago and those built in Tudor times. They had to identify parts of the castles - including the moat, battlements, arrow slits and drawbridge - before they were challenged to build their own castle using Lego.
The features of a castle that had been discussed had to be included, but some children used their imagination to also include ornamental gardens, prisons, working doors and even a guillotine.
Finally, the castles were judged based on effective team work and who had built the most authentic castle.
