Turtle is joined by Ultan Cowley who shares his insights into the daily lives, motivations and semi-mythological reputations of the Irish navvies who built the canals, and how their successors built Britain’s railways, motorways and the Channel Tunnel.

Started on the eve of the French Revolution, the Royal Canal is Ireland’s longest manmade waterway running for 145 km (90 miles) from Dublin to the River Shannon. Here Turtle tells the colourful story of its founders Long John Binns and William Cope, and looks at why it took almost 30 years to finish the project.

Featuring cameos by James Joyce’s canal-building forbear and Black Tom Wentworth, we learn how the desire to drain and improve Ireland’s boglands led the industrious Georgians to slowly (very slowly) construct some of the island’s earliest canals and waterways.

Patsy Cummins is the third generation of her family to work on the Grand Canal. Having been keeper of the 29th lock near Tullamore, she talks of the friendships she made along the way and explains how a tragedy at Shannon Bridge brought her family east to Ballycowan.

Dive into this gorgeous interview with Gwen Wilkinson, who named her homemade boat ‘Minnot’ before setting out on her 400 km journey from the shores of Lough Erne to the tidal waters of the River Barrow in Ireland.
