Perthshire Scotland.
Roman fort at
the confluence of the Tay and Almond; the pseudo-Latin
name is a 14th c. invention. Subject to riverine erosion,
it measures ca. 255 by at least 150 m, but the surviving
stretch of the SE rampart is of slighter build than that
on the NW, and may be a late feature reducing the area
of a still larger fort. The site has not been excavated, but
has produced an inscription attributable to the 2d c. A.D.
