The lack of written sources and the difficulties of establishing close chronologies from archaeological material mean that it is difficult to identify initiatives other than the commissioning of Hadrian's Wall that can confidently be attributed either to the emperor's visit to Britain in 122 or to his reign more generally. However, the early second century presents several archaeological proxies which point to a quickening of economic activity integrating the frontiers of Wales and the north of Britain with the civil zone of the south. Developments in the countryside hint at the growth of larger estates, including the emergence of larger, ‘complex’ farms, villages and better communications, together assuring the province's sustained ability to feed both military and civilian populations. At the same time there is evidence for public building across the towns of the south, especially of forum basilicas, which may be linked to administrative reforms including the establishment of new civitates.
