In the archaeological collection, finds from all time periods are represented. Finds from the well known Neolithic axe factory site of Graig Lwyd are on display. The hand axes from the Graig Lwyd site near Llanfairfechan have been found from all over Britain – even as far as Cumbria and they tell us a lot about the technology and the distance of ideas and items all over Britain.
There are a large number of items dating to the Bronze Age (c.2500- 1000 B.C) in the collections, funerary remains and urns from sites such as Bedd Branwen.
The nearly intact Roman sword found at the fort of Segontium is particularly unique, as are the imperial milestones from the Roman road between Aber falls and Caernarfon.
Early Christian memorials including the Llantrisant Stone which has inscribed the longest obituary notice from Britain. The museum also has a number of beautifully patterned medieval tiles from Llanfaes and medieval finds from Owain Glyndwr’s home at Sycharth.
