I have noticed this mural a number of times but what I never noticed was that the street is closed to through-traffic. I checked online and here is the description that I found: "The street "Stirrup Lane" is located in the southeast of Dublin 7. It is about 72 meters long and the maximum speed here is at 30 km/h." I checked some photographs from February 2019 and they were no planters blocking through-traffic.
