Welcome to the historic city of Derry – or Londonderry, depending on who you ask. Ours is a city rich in complex history, and filled with locals who’ll invite you to stay and "enjoy the craic".

This self-guided GPS audio tour takes you on a full circuit of the city's 400-year-old walls. I’ll point out many of the famous historical and cultural sights en route and suggest places to return to for longer visits.

You may know a bit about the city from the recent comedy series Derry Girls, and we’ll visit the popular mural dedicated to the show. But on this tour you’ll also hear about:

• The city's saint, St Columba / Colmcille, who first established his monastery here in 542 AD
• The great Siege of Derry in 1688 and 1689
• The Troubles, which were a part of life here from 1969 to 1994
• The city's role in the second world war and the Battle of the Atlantic
• Immigration during the Plantation of Ulster
• Emigration during the Irish Potato Famine, or Great Famine, from 1845 to 1849
