This is an ongoing and continuous dig to excavate, record and understand the development of Trellech, once the largest settlement in Wales. The dig started more than 10 years ago and has discovered several stone buildings from the medieval city including a fortified moated manor house that has been the focus of recent excavations. Trellech was a planted industrial town created by the De Clares in 1245 for the conquest of Wales. Occupation on the site lasted until c.1650 with finds from other periods occasionally found.
Excavation occurs from April through to October with a concentrated 4 week summer dig that is open to students. Student and annual memberships are available. The dig also runs Experience Days that allows anyone an enjoyable and immediate opportunity to become an archaeologist for a day and dig on a real site.
