We can read on the various signs:

A dedication to Saint Thomas Becket
The Aizier leprosarium is dedicated to Saint Thomas Becket.
Archbishop of Canterbury, familiar with King Henry II of England, he came into conflict with the latter and was forced into exile in France.

Back in England he was assassinated on December 29, 1170 in his cathedral. He was canonized on February 21, 1173.
The various miracles attributed to him justify his many hospital patronages, particularly in Normandy.

Saint-Thomas chapel in the Middle Ages
The chapel was built around 1180. In the Middle Ages, it was then the center of community life. Lepers, considered impure, indeed needed a place of worship of their own since they could not enter public places.

Although each leper colony had its own organization
The establishment of Aizier is a privileged witness to this emblematic disease of the Middle Ages.
The site is all the more interesting in that it has not evolved since its abandonment in the 16th century.
It has therefore come down to us fossilized.

Aizier, a modest leper colony
The leprosarium of Aizier is of modest size. Estimates obtained from burial excavations suggest an average of 3 to 4 lepers permanently residing at the site
