A medieval guildhall.  The majority of the Hall was built
in 1357 by a group of influential men and women who
came together to form a religious fraternity called the
Guild of Our Lord Jesus and the Blessed Virgin Mary.
In 1430 the fraternity was granted a royal charter by King
Henry VI and renamed 'The Mistry of Mercers'.  It was
granted the status of the Company of Merchant Adventurers
of York by Queen Elizabeth I in the sixteenth century.
The main part of the building consists of the Great Hall
and the undercroft, which was originally a hospital
or almshouse for poor people of York.
