Sandymount was originally named Scallet Hill, and was owned by Richard de Saint Olof in the 1200s. The local soil was discovered to be excellent for making bricks and in the 1700s it became known as Brickfield Town when a brick manufacturing industry was based there. In the late 1700s James Gandon designed Sandymount Park.
