The historical marker outside the library (
visit link) indicates:
"The Falls Road branch (1905-08) is one of three Carnegie libraries in Belfast. The others are situated on the Oldpark Road (1905-06) and Donegall Road (1907-09). They were all designed by architects, Graham-Watt and Tulloch. The Falls Road branch opened on 2 January 1908 and is a fine example of the English Classical style. Spandrel angels over the entrance are by the gifted Irish artist, sculptor and writer, Rosamund Praeger (1867-1954). Praeger also designed the female figure plaques of 'Art' and 'Literature' on the front door. Attention to detail continues inside, with fine art nouveau ironwork on the stairway."
