Mentioned by IRELAND ON A BUDGET
Dublin's Free Museums and Galleries
"The gallery, which was established in 1864, houses an extensive collection of Irish, Italian Baroque, and Dutch masters paintings. During normal times, a good way to see the gallery is to take a free guided “Highlights Tour,” which includes highlights of the gallery’s permanent collection. It is normally offered six times a week, on Thursdays at 6:30 p.m., on Saturdays at 12:30 p.m."
