The Ultimate 2 Days In Dublin Itinerary
"Chester Beatty Library is located directly adjacent to the Dublin Castle and is free. It houses the collections of Sir Charles Beatty, who made his name in mining. Admission is free, and guided tours are available for a fee, but check the tour times when you plan to visit so you can adjust your day accordingly. The treasures are displayed in two collections, “Sacred Traditions” and “Artistic Traditions.” Upon his death, Mr. Beatty bequeathed these priceless and sometimes rare items to the Irish People."
