Overview

History & context

Inchtuthil, traditionally identified with the Pinnata Castra ("fortified camp") mentioned by Ptolemy, was a legionary fortress built around AD 83–84 in the aftermath of Agricola's victory at Mons Graupius, intended as the permanent base of Legio XX Valeria Victrix in northern Caledonia. Covering some 21.5 hectares (53 acres) on a plateau above the Tay, it included barracks for ten cohorts, granaries, workshops, a hospital (valetudinarium), and headquarters buildings, but was systematically demolished and abandoned around AD 86–87 before it was ever fully completed, almost certainly because troops were withdrawn to meet a Danubian crisis.

Archaeology

Archaeological record

Excavations by Sir Ian Richmond and J.K. St Joseph between 1952 and 1965 produced one of the most complete plans of any early imperial legionary fortress, revealing the meticulous demolition of buildings and the famous hoard of around 750,000 unused iron nails (some 7 tonnes) buried in a pit to deny them to the natives.
