[5][6] Maughanasilly Stone Row was erected during the Bronze Age, c. 1600–1500 BC, making it contemporary with the Indo-Aryan migrations and the rise of Shang China, the New Kingdom of Egypt and Mycenaean Greece.

It was used for archaeoastronomical purposes, for making observations of lunar standstills and equinoxes.

[9][10] Shallow pits were found with quartz pebbles scattered around.
