Dobe (Incēni) Hillfort, the centre of Land Dobene and the main fortification, was inhabited by Semigallians since the 1st millennium. A settlement once spread at the east and southeast of the hillfort foot, and the largest archaeological findings in Latvia are a proof of that. It is believed that the ancient Semigallian hillfort was built on one of the hillocks of Dobe Hillock chain, but its position in the middle of the field and how the hill stands out in the surrounding landscape allows to suggest that Dobe Hillfort is among the rare artificial hillforts of ancient times. Approaching the hillfort, its distinct shapes can be seen from afar. To understand at what distance an approaching enemy is seen, one shall climb on the rampart of the hillfort. It offers spectacular views of the surrounding.
