Back is August 2019 An Bord Pleanála was set to rule on the case of a well-known mural in the Smithfield area after Dublin City Council found that it needs planning permission to remain in place. At the time a petition gained over 2,500 signatures in two days but despite this the appeal to An Bord Pleanála was withdrawn and an enforcement order was issued by the council. It is now January 2022 and the mural is still on view. 

Stirrup Lane is a very old side street off Church Street. It was "probably named after a family who resided in this area" according to Paul Clerkin's book Dublin Street Names but if I had to make a guess I would say that the name relates in some way to horses.
