The stone circles, building remains, and storage pits

Numerous remains of dug-standing pillar buildings and flask-shaped pits have been found within 24 m of the Manza stone circle. This ring is divided into three parts with the following tendencies: ring one (6 m width) with six-pillar buildings, ring two (6 m width) with four-pillar buildings, and ring three (12 m width) with many flask-shaped and other pits in the ground. Since these buildings do not have fireplaces, are accompanied by tools for festivals and prayer, and are located near the stone circles, it is thought that they were constructed to hold festivals and for praying. The flask-shaped pits were used to store food during the festival period, and contain sweet chestnuts, walnuts, and horse chestnuts.
