What about Quinn’s Lane that links Fitzwilliam Square with Leeson Street. There are still residents living there and a derelict building beside Good Mood Cafe that looks like an old school. I would love to hear the history of this place:-)
it was actually the old st vincent hospital not a school!
My favourite lane in Dublin is the “Long Lane” at the side of the old Meath hospital leading onto the junction of Clanbrassil St and New St from Heytesbury St. It has perhaps the smallest house in Dublin at 19a Long Lane with the distinction of the house being built on the plot of land that was…yes; you have guessed it, a laneway! The laneway was originally known as Heytesbury Place. Perhaps someone spotted a literal gap in the market and built a house on it!
