ron Age architecture is relatively poorly represented in the bend of the Loire, very probably because of the nature and state of preservation of the structures and because extensive archaeological excavations were not possible until relatively recently. Comprehensible plans of post-built buildings are known from different phases of the Iron Age, but are only known in small numbers. It is essential also to envisage structures that were not dependent on earthfast timbers and which therefore have not left clear traces. An exceptional find is a wall of unfired clay at Bourges. Semi-sunken structures, notably workshops, are common in both the First and Second Iron Ages. Significant concentrations of them have been identified in both the 5^th and the 2^nd c. BC. Groups of substantial storage pits are known in the 4^th and 3^rd centuries. A few farms have been identified in the Champagne berrichonne, but these are rarely excavated. These modest range of remains seems to fit into the classic types of the Iron Age of the Paris Basin and eastern France.
