Since the 1960's Ronald Edgar Remfry (1918-2004) and his son, Paul Martin Remfry, have built up a large series of slides covering the development of castles in Normandy and the British Isles. Paul is always willing to give talks illustrated by slide shows on castles in general or under wider remits. From this Paul can show you things like the development of castles from the early pre-1066 motte and baileys like Richards Castle to the last of the military forts like Aberedw. Other themes can be followed like the military evolution of a district or county. If you do not see the castle you are interested in please get in touch. We can then see if it is possible to add your subject to the list and so enable me to make a display for your group or society.
The many slides are listed below by county.
