smaller streets to Ash St. and back to the Coombe. In 1837 the Ordnance Survey started developing their maps, and that of Dublin published in 1840 showed all the liberties, from the smallest (Christ Church Liberty, one acre and two roods) to the largest (the Earl of Meath's Liberty, 380 acres). Privileges In return for the support of the ruler of the liberty, or to alleviate certain hardships suffered by Englishmen or the church in Ireland, privileges were granted to the rulers of the liberties at various times and by various kings of England. For example, these allowed the liberty of St. Sepulchre to have its own courts of justice (Courts Leet, Courts Baron and a Court of Record, where it was allowed to try all crimes except "forestalling, rape, treasure-trove and arson"), free customs, freedom from certain taxes and services, impose their own fines, have their own coroners, rights of salvage, maintain their own fairs and markets, regulate weights and measures, etc. These rights and privileges ended in 1840. Historical developments Many places in The Liberties still have connections with a turbulent past in which political upheaval or dire poverty were the order of the day. In the 17th century, parts of them became wealthy districts, when the weaving crafts of the immigrant Huguenots had a ready market around the present day Meath Street Market, and a healthy export trade. 17th and 18th centuries In the late 17th century development started in order to house the weavers who were moving into the area. Woollen manufacture was set up by settlers from England, while many Huguenots took up silk weaving, using skills they had acquired in their home country, France. They constructed their own traditional style of house, Dutch Billies, with gables that faced the street. Thousands of weavers became employed in the Coombe, Pimlico, Spitalfields and Weavers' Square. However, English woollen manufacturers felt threatened by the Irish industry, and heavy duties were imposed on Irish wool exports. The Navigation Act was passed to prevent the Irish from exporting to the whole colonial market, then in 1699 the English government passed the Wool Act which prevented export to any country whatsoever, which effectively put an end to the industry in the Liberties. A weavers' hall was built by the Weavers' Guild in the Lower Coombe in 1682. In 1745 a new hall was provided, financed by the Huguenot, David Digges
