This paper presents the results of a series of geophysical surveys of Roman forts and their environs carried out by the Gwynedd Archaeological Trust. An almost complete plan of the early wooden fort at Llanfor has been produced. Its densely-packed interior demonstrates heavy garrisoning, probably during very early Flavian campaigning. The small square auxiliary fort of Caer Llugwy has been shown to be a contraction of a larger rectangular fort. Surveys at Pennal, Caer Gai, and Canovium revealed a wide range of extramural development including vici in the form of ribbon development.
