A market cross, or in Scots, a mercat cross, is a structure used to mark a market square in market towns, where historically the right to hold a regular market or fair was granted by the monarch, a bishop or a baron.  Market crosses were originally from the distinctive tradition in Early Medieval Insular art of free-standing stone standing or high crosses, often elaborately carved, which goes back to the 7th century.  Market crosses can be found in most market towns in Britain.  British emigrants often installed such crosses in their new cities, and several can be found in Canada and Australia.

However, Jews were excluded from residency in a number of cities within the Pale, and a limited number of categories of Jews—those ennobled, with university educations or at university, members of the most affluent of the merchant guilds and particular artisans, some military personnel and some services associated with them, as well as the families, and sometimes the servants of these—were allowed to live outside it.
