It is situated next to the village of Seavington St Michael, about 3 miles (4.8 km) east of Ilminster, within the South Somerset district and had a population of 384 inhabitants at the 2011 census.

Seavington St. Mary SSSI is a geological Site of Special Scientific Interest where there are extensive exposures through much of the Inferior Oolite.

It is thus of considerable importance in interpreting the local stratigraphy and sedimentology in relation to the palaeogeography of south-west England in Middle Jurassic times.

[6] The former Anglican parish Church of St Mary has 13th-century origins, but the current building is largely from the late 15th century, with restoration around 1880.

[8] It was previously held as a chapelry of South Petherton by Bruton Abbey and after the dissolution of the monasteries belonged to Bristol Cathedral.
