A history-rich city day for teenagers: walk the complete 17th-century walls, explore the city's story and an Armada wreck at the Tower Museum, lunch in the Guildhall, then visit the Museum of Free Derry in the Bogside.
Walk the full circuit and spot the cannon on the ramparts.
The only complete set of 17th-century city walls in Ireland, about a mile round, with cannon along the ramparts and views over the Bogside murals. Walking the full loop is free and takes about an hour with stops.
Derry's red sandstone Guildhall, just outside the walls, with stained glass, a café and free-to-browse exhibitions. A paid Derry Girls exhibition and short guided tours are also offered.
A powerful look at the civil rights era; best for older teens.
A Bogside museum covering the civil rights era and the early Troubles, including Bloody Sunday. Its subject matter makes it a thoughtful visit for teenagers rather than younger children.
