Bangor

Paul Martin is joined by a team of experts led by Mark Stacey and Adam Partridge in Bangor, north Wales. Together they value items including a collection of thimbles and an antique sextant.

Paul also pays a visit to the Menai suspension bridge, which spans the treacherous Menai Strait that separates Anglesey from mainland Wales. The incredible feat of engineering was the work of Thomas Telford, widely considered to be 'the man who built Britain'.
