A New Plan Of Dublin (1769)

This beautifully drawn map, now almost 250 years old was included as part of Hibernia Curiosa: A Letter from a Gentleman in Dublin to his Friend at Dover in Kent, giving a general View of the Manners, Customs, dispositions, &c., of the Inhabitants of Ireland, with occasional observations on the State of Trade and Agriculture in that Kingdom, And including an account of some of its most remarkable Natural Curiosities, such as Salmon-Leaps, Water-Falls, Cascades, Glynns, Lakes, &c.; with a more particular description of the Giant’s Causeway in the North; and of the celebrated Lake of Killarney in the South of Ireland; taken from an attentive survey and Examination of the Originals; collected in a tour through the Kingdom in the years 1764.  I think the author was going for a Ronseal effect with that long winded title. The book was written by John Bush Of Tunbridge Wells, perhaps an ancestor of the latter day Disgusted Of Tunbridge Wells. The map would still be somewhat helpful guiding a sojourner around Dublin's inner city but as you get further from the centre it becomes less useful as an aid to navigation.

A few things worth mentioning:

No sign yet of O'Connell Bridge and O'Connell Street was still divided into several different names, Drogheda St. and Sackville Street. 

The area from Blackhorse Lane (now Avenue) on the top left across to Dorset Street was still given over primarily to agriculture. 

What latterly became known as Foley Street is marked on the map as World's End Lane.

What's now known as Island Street (near Ussher's Island) was once the far more evocatively named Dunghill Lane.

At the bottom left of the map, which mainly has agricultural lands, there's a Cuthroat Lane. As best I can tell this street no longer exists. It latterly became Roundhead Row and then I think was removed to make way for the hospital. Edited to add: It seems that Cuthroat Lane now goes by the name of Brookfield Road, how dull! Just north of this street is Murdering Lane, which still exists and now goes by the name Cromwell's Quarters.
