The Inner Enclosure housed elites and protected the most valuable goods, including amber, trading beads and bronze. Cotter found bronze hoards in the inner enclosure. The upper classes buried these valuables to control the circulation of bronze, the most important currency, much the way the government controls money today. An extra wall was erected on the west, where the outer wall was closest to the inner wall, therefore provided the shortest attack route. In other words, Dun Aengus’s architects were assessing risk.”]
