GRAND CANAL PLACE [WAS AN END POINT FOR THE GRAND CANAL]
Originally Pim Street was part of Grand Canal Place.
The curved profile of the boundary wall reflects the plan of the surrounding area, which grew around the Grand Canal Harbour. The Guinness Brewery was founded in 1759 by Arthur Guinness when he purchased brewery buildings south of Saint James's Gate from Mark Rainsford. It subsequently expanded on all sides, and was at one time the largest brewery in the world.

To the best of my knowledge I have not walked the full length of this curved street until today.
The area which is south of James Street includes the original St James’s Gate Brewery and the original terminus of the Grand Canal. The area straddles the east edge of St James’s Hospital and the main commercial streets of The Liberties.
The area will see major changes in the coming years. For example, Diageo announced plans in 2017 to develop 12.6 acres of the iconic complex at St. James's Gate into an urban centre complete with housing, offices, and shops called the "Guinness Quarter."

It passes through Ringsend and traverses the southside, delineating the northern extremities of Ballsbridge, Ranelagh, Rathmines, Harolds Cross and Crumlin. This section, known as the Circular Line (or Circle Line), has seven locks. The path of the original main line, which serviced the Grand Canal Harbour, the City Basin (reservoir) and Guinness brewery, can be seen at Inchicore. Most of the route of this line now runs alongside the Red Luas Line.
