Celts did not prove in creation of large political formations of the state character, in monumental architecture. Celts were not creators of architectural monuments of monumental character, they were only builders of fortresses which speak about their organizing abilities and are result of well organized work of huge collectives. Usual systems of strengthening in the Celtic world were built according to ancient local traditions. The typical Gallic wall described by Caesar which is geographically limited to certain areas of the Celtic world it was mentioned already in chapter about oppidum. Where nevertheless constructions of representative or monumental character were built, it happened under others influence and to others help. It took place at construction of fortress with bastions in Heuneburg during the last-hallstatt period and at constructions on the South French coast during the Latin period. In so-called Celtic architecture and a sculpture it is necessary to distinguish essentially the southern French territory in the neighborhood of Massiliya and in the lower current of Rhone, in essence Celtic-Ligurian, from actually Celtic internal areas, since France on the East on the Czech lands and the Carpathian hollow.
