The publication in 1911 of James Curle's excavation of the Roman frontier fort of Newstead, ancient Trimontium, near Melrose in the Scottish Borders was a landmark in Roman frontier studies. This volume (in a new paperback edition) was conceived as a celebration of this landmark on its centenary, looking back to Curle and his work, and looking forward to how the picture is changing. It is constructed around five main themes: Early work on the site; the fort complex; the finds; the setting, especially links to the local population; the afterlife of the excavations, in terms of their continuing impact.
