Unfortunately I cannot located any information relating to the artist.
This is located at Chesterfield Avenue but I suspect that most people would know this as Parkgate Street.
Park Gate is the one of the principal entrance gates to Phoenix Park. Lying at the park’s southeast corner it opens to Chesterfield Avenue, which bisects the parkland. The gateway comprises four stone piers which have been repaired in recent years. They are generally plain in treatment save for the carved caps and glass lanterns. The piers were taken down to facilitate access by the crowds attending the Eucharistic Congress of 1932. Park Gate is part of the historic fabric of Dublin's celebrated Phoenix Park and contributes significantly to the visual and monumental character of this designed landscape.
