Barnaby visits the city of Dublin in the Republic of Ireland. Since he is only going for a few days he flies rather than going by ferry. Once in Dublin he visits a number of the city's attractions, including the Smithfield Chimney. He finds that making a simple map helps him get around, and that there a many ways to travel around the City. He goes on a bus tour of the city, and goes on the DART. Finally he goes Irish dancing.
