Dún Laoghaire dates from the 1820s. An earlier Dún Laoghaire village was around the area where the Purty Kitchen pub is now (sometimes mapped as "Old Dunleary"). Dún Laoghaire had a coffee house and a small cove, both of which are shown on a number of old maps, and it may have had a salt mine (Salthill is close by). At that time, the area was a craggy, rocky pasture with some quarries.
