[2] On the hills northwest of the village are the earthworks of Buzbury Rings (or Busbury Rings), the remains of an Iron Age and Romano-British fortified encampment or settlement,[3][4][5] described by Sir Frederick Treves in 1905 as "a circle of entrenchments, composed of a stout vallum and a ditch".

[5] The outer enclosure covers about 10 acres (4 hectares) and within this is an inner enclosure, covering about 3 acres (1.2 hectares), which is the location of most of the finds from the site, including Roman pottery, animal bones and daub imprinted by wattles.

[4] The village's parish church has a 15th-century tower, though the rest of the building was rebuilt in 1852 by Thomas Henry Wyatt.

[3] The Bishop of Salisbury Richard Poore is most likely to have been buried at Tarrant Keyneston in accordance with his wishes.

[6] Almost all of Tarrant Keyneston parish is within the Cranborne Chase and West Wiltshire Downs Area of Outstanding Natural Beauty (AONB).
