Light Square is one of five squares in the City of Adelaide. Located in the centre of the north-western quarter of the Adelaide city centre, the Square is named after the city's planner, Colonel William Light.
The Square is divided into a number of sections separated by roads. Waymouth Street (runs east-west) forms the Southern boundary of the Square. Currie Street (east-west) divides the southern two-thirds of the square from the northern third. Morphett Street (north-south) splits into dual-carriageway and encircles the square.
In the largest southern section, (nearly two-thirds of the Square), Colonel Light is buried beneath a monument consisting of a red granite monolith topped with a surveyor's theodolite. Also, there is a bronze statue of Catherine Helen Spence in the southwest corner of this southern section, and an artistic structure on the western edge.
