North Wales (S02E03)

Rob heads to Bangor in North Wales to uncover a forgotten railway line established in 1801, originally designed to carry Welsh slate from a quarry that was once the largest globally. This area now serves as the setting for the world’s fastest zip line. He then traces the Victorian railway to Llanberis, where visitors continue to ride a unique train that ascends Snowdon's peak. Along the way, Rob learns about the historical significance of the title "Prince of Wales," which has been held by royal heirs for seven hundred years.
