26 carefully positioned fire-pits indicate the location of a Roman marching camp situated near a river crossing and on a terrace of the river Ayr, South Ayrshire, Scotland. Radiocarbon dates from six of the pits provided dates ranging from 2 b.c. to a.d. 231, with an overlap around the Flavian period (a.d. 77–86 to 90). There is some evidence for the clay superstructure of ovens, and botanical evidence for the fuel used and crops cooked.
