The Roman fort at Mollins lies at about 75 m above sea level, on the south bank of the Luggie Water, a major tributary of the River Kelvin (FIG. I). The site (National Grid reference NS 714 719) lies on the side of a small ridge, and faces northwards over gently undulating ground. The substratum is glacial till and, although the site is moderately well drained, under natural conditions the broad flood plain of the Luggie Water, which borders onto the northern edge of the fort, would have been formerly very poorly drained.
The archaeological site comprises a Roman fort which was probably built and later deliberately demolished during the Agricolan campaigns around a.d. 80 to 90.
