I took a break from the conference to go and look around Waltham Abbey famous as the burial place of Harold Godwinson (he usurped the throne as Harold II although I think William the Conqueror had a much more legitimate claim to the throne).
The heat and humidity were debilitating and enervating.
Looking towards the High Altar you can see one of the huge Norman columns that support the structure.
You would think that in such a stone building it would be cool, but there was no respite from the heat.
Up a short flight of steps to an elevated chapel to see the 15th century Last Judgement mural. It was a wonderful experience to see this painting. This is one of the wonders of north London.
It needs to be conserved properly.
