A tron was a weighing beam in medieval Scotland, usually located in the marketplaces of burghs. There are various roads and buildings in several Scottish towns that are named after the tron. For example, Trongate in Glasgow and Tron Kirk in Edinburgh. Etymologically the word is derived from the Old French tronel or troneau, meaning "balance". [1]


Measurement of weight in medieval Scotland

From the 12th century the city fathers of Scottish burghs needed to standardise weights and measures, partly to collect the correct taxation on goods, and partly to stop unscrupulous merchants shortchanging citizens. Trons were set up in marketplaces throughout Scotland. Each burgh had its own set of weights, which sometimes differed from those of other burghs. [1] Some burghs had more than one tron; in Edinburgh a butter tron was located at the head of the West Bow, while a salt tron was located further down the Royal Mile. [2] [3]

Scottish units

Scottish or Scots units of measurement are the weights and measures peculiar to Scotland which were nominally replaced by English units in 1685 but continued to be used in unofficial contexts until at least the late 18th century. The system was based on the ell (length), stone (mass), and boll and firlot (volume). This official system coexisted with local variants, especially for the measurement of land area.

The Canongate is a district of Edinburgh, the capital city of Scotland.

The Canongate is a street and associated district in central Edinburgh, the capital city of Scotland. The street forms the main eastern length of the Royal Mile while the district is the main eastern section of Edinburgh's Old Town. It began when David I of Scotland, by the Great Charter of Holyrood Abbey c.1143, authorised the Abbey to found a burgh separate from Edinburgh between the Abbey and Edinburgh. The burgh of Canongate that developed was controlled by the Abbey until the Scottish Reformation when it came under secular control. In 1636 the adjacent city of Edinburgh bought the feudal superiority of the Canongate but it remained a semi-autonomous burgh under its own administration of bailies chosen by Edinburgh magistrates, until its formal incorporation into the city in 1856.

Old Tolbooth, Edinburgh street in Edinburgh, United Kingdom

The Old Tolbooth was an important municipal building in the city of Edinburgh, Scotland for more than 400 years. The medieval structure, which was located at the northwest corner of St Giles' Cathedral and was attached to the west end of the Luckenbooths on the High Street in the Old Town, was first established in the 14th century by royal charter. Over the years it served a variety of purposes such as housing the Burgh Council, early meetings of the Parliament of Scotland and the Court of Session. The Tolbooth was also the burgh's main jail where, in addition to incarceration, physical punishment and torture were routinely conducted. From 1785 public executions were carried out. In 1817 the buildings, which had been rebuilt and renovated several times, were demolished.

Economy of Scotland in the Middle Ages

The economy of Scotland in the Middle Ages covers all forms of economic activity in the modern boundaries of Scotland, between the End of Roman rule in Britain in the early fifth century, until the advent of the Renaissance in the early sixteenth century, including agriculture, crafts and trade. Having between a fifth or sixth of the arable or good pastoral land and roughly the same amount of coastline as England and Wales, marginal pastoral agriculture and fishing were two of the most important aspects of the Medieval Scottish economy. With poor communications, in the early Middle Ages most settlements needed to achieve a degree of self-sufficiency in agriculture. Most farms were operated by a family unit and used an infield and outfield system.

Tolbooth the main municipal building of a Scottish burgh, from medieval times until the 19th century.

A tolbooth or town house was the main municipal building of a Scottish burgh, from medieval times until the 19th century. The tolbooth usually provided a council meeting chamber, a court house and a jail. The tolbooth was one of three essential features in a Scottish burgh, along with the mercat cross and the kirk (church).

The Convention of Royal Burghs, more fully termed the Convention of the Royal Burghs of Scotland, was a representative assembly which protected the privileges and pursued the interests of Scotland’s principal trading towns, the royal burghs, from the middle of the 16th century to the second half of the 20th century. It evolved as a forum in which burgh delegates, termed "commissioners", could "consult together and take common action in matters concerning their common welfare" before and during the sittings of parliament. An exclusively merchant body, it was essentially a parliament which "declared the law of the burghs" just as the Scottish Parliament "declared the law of the land". The Convention expanded over time by admitting lesser burghs to its membership; and by the 16th century had grown in influence to the extent that "it was listened to rather than directed by the government". Though still known as the "convention of royal burghs", it referred to itself from the late 17th century onwards as simply the "convention of burghs", as by then membership was no longer restricted exclusively to royal burghs and commissioners from all types of burgh were represented in parliament.
