Overview
Georgian Dublin is a phrase used in terms of the history of Dublin that has two interwoven meanings:
to describe a historic period in the development of the city of Dublin, Ireland, from 1714 (the beginning of the reign of King George I of Great Britain and of Ireland) to the death in 1830 of King George IV. During this period, the reign of the four Georges, hence the word Georgian, covers a particular and unified style, derived from Palladian Architecture, which was used in erecting public and private buildings
to describe the modern day surviving buildings in Dublin erected in that period and which share that architectural style
Though, strictly speaking, Georgian architecture could only exist during the reigns of the four Georges, it had its antecedents prior to 1714 and its style of building continued to be erected after 1830, until replaced by later styles named after the then monarch, Queen Victoria, i.e. Victorian.
Dublin's development
Dublin was for much of its existence a medieval city, marked by the existence of a particular style of buildings, built on narrow winding medieval streets. The first major changes to this pattern occurred during the reign of King Charles II when the then Lord Lieutenant of Ireland, the Earl of Ormonde (later made Duke of Ormonde) issued an instruction which was to have dramatic repercussions for the city as it exists today. Though the city over the century had grown around the River Liffey, as in many other medieval cities, buildings backed onto the river. This allowed the dumping of household waste directly into the river, creating a form of collective sewer. As Dublin's quays underwent development, Ormonde insisted that the frontages of the houses, not their rears, should face the quay sides, with a street to run along each quay. By this single regulation Ormonde changed the face of the city. No longer would the river be a sewer hidden between buildings. Instead it became a central feature of the city, with its quays lined by large three and four-storey houses and classic public buildings, such as the Four Courts, the Custom House (1707) and, later and grander, Custom House designed, as was the Four Courts, by master architect James Gandon. For his initiative, Ormonde's name is now given to one of the city quays.
It was, however, only one of a number of crucial developments. As the city grew in size, stature, population and wealth, two changes were needed.
