Although this one-place study focuses on the period with documentary evidence that can be studied and transcribed, especially before 1820, there is also an interest in the wider chronological history of Melrose and the surrounding area. And that includes extending far back in time before documentary evidence is available.
One of the most famous sites in the Melrose area is the Roman fort of Trimontium, which was excavated in the early 20th century. There is now a permanent Trimontium museum in the town, and the Trimontium Trust promotes the site and its history.
So I’m pleased to be able to say that the 1911 excavation report for Trimontium is available freely online. See here, in particular the link to the PDF page. PDFs of individual chapters are available, or a single 400+ page PDF of the whole book can be downloaded.
