# International Castle Research Society

The International Castle Research Society (ICRS) was established in Aachen in 1986 as a not-for-profit organization following earlier initiatives by Bernhard Siepen, architect, who has been its president since 2000. Early supporters were the long-standing Aachen member of parliament, Dr. Hans Stercken, and Consul Cornel Renfert, of the Franco-German Chamber of Commerce, Paris.

## Background

The first model, the Donjon of Coucy, was started in 1997, with a number of models following, the latest being the Castel del Monte. Whereas the earlier models were of French fortified keeps, or donjons, then Crusader castles and bazaars as well as medieval ships, for some time now ICRS has been working on creating models of palaces typical of the 9th to 12th centuries. There are also plans for a model of the imperial Aachen palace of Charlemagne, dating from around AD 800, and of historic buildings in Jerusalem.

## ICRS activities

The president, team and ICRS consultants:
* create models of historic buildings, ships, life- scenes
* bring these models to life peopling them with hand-painted figurines
* present models, descriptions, plans of important castles
* organize seminars, talks, multimedia shows as well as visits to exhibitions and existing historic buildings
* support and organize research study courses on historic buildings at school and university level
* train young people in handicrafts relating to creating models
