"Running tours since 1986, they use guides with postgraduate history qualifications who pair serious knowledge with a good Irish sense of humor; each walking tour is just over two hours, they start from the front gate of Trinity College at 11am every day (Fri–Sun only in winter) with an extra 3pm tour from May to September, they take you to highlights like the House of Lords, Temple Bar, Christ Church Cathedral, and Dublin Castle, and tickets are 19 EUR — a great overview of Irish history." - Matthew Kepnes
