The transition between the Late Hallstatt Period and the Early La Tène Period represents a notable phase of the Moravian prehistory. It is associated with the concept of the so-called 'first Celtic expansion' as promoted by Miloš Čižmář.
The current sources on the 5th century BC confirm the discontinuity of development in Ha D3 and LT A; and the expansion concept was recently confirmed by Petra Goláňová. Adding to the topic, Martin Golec and Zuzana Mírová have brought up the yet ignored aspect of central site with the continuity of elites during Ha D1-D3 at Habrůvka - 'Býčí skála'.
The social system during the late Hallstatt period in Moravia can be defined as largely centralised, which conforms to P. Goláňová's theory on LT A.
The Provodov - 'Rysov' hillfort provides ample evidence in the form of finds dating to Ha D1 - LT A and is discussed within the framework of this topic.
