Tassiesholm (Milton), in Annandale, was a Roman auxiliary fort situated on the main road from Carlisle to the Clyde (the route later known as the "Watling Street" of southern Scotland). It saw multiple phases of occupation from the Flavian period (c. AD 80s, under Agricola's northern campaigns) through the Antonine period (mid-2nd century), reflecting the recurring Roman push into southern Scotland.

The fort was a key garrison post controlling the strategic corridor up Annandale between the major bases at Birrens to the south and Crawford to the north, and formed part of the network of forts supporting both the Agricolan advance and the later Antonine Wall frontier. Its repeated reoccupation underlines Annandale's importance as the principal western land route into Caledonia.
J. Clarke's excavations of 1938–50 identified a complex multi-period site including the fort itself, an annexe, and associated bathhouse and external structures, with evidence for Flavian, Antonine I and Antonine II phases distinguished by successive defensive circuits and internal rebuilding. Finds included pottery, coins and military equipment consistent with auxiliary occupation, though the full results were never comprehensively published, leaving aspects of the internal plan and garrison identity uncertain.
