A Caernarfon Roman fort has been restored to its former glory thanks to CGI technology.
Historic monuments body Cadw has created a video to show how Segontium looked around 70 AD.
The video superimposes the fort on the town's landscape as it is today for a sense of scale.
Caerphilly Castle was restored thanks to CGI in July as part of Cadw's Time Traveller campaign.
