It is located 14 kilometers from the county capital Pärnu, on the left coast of the Pärnu river. The area of what is now Sindi was the site of the Mesolithic settlement of Pulli, dating from around 8500 BCE – the oldest known settlement in Estonia. It was discovered by geologists in 1965. The settlement probably existed for a short period, as the area was later covered by water. As a swampy region, the area remained unpopulated until the 16th century.
