The National Gallery of Ireland is a tranquil escape in the city's Georgian Quarter, housing the nation's priceless art collection. Entry to the permanent collection is completely free, making it an easy and worthwhile addition to any itinerary. The gallery's vast collection of over 16,000 pieces spans from the 1300s to the present day, featuring masters like Caravaggio, Vermeer, and Monet. It is manageable without being overwhelming and offers a peaceful retreat from the bustling city streets. A major highlight is Caravaggio's The Taking of Christ, a masterpiece with a fascinating history—it was famously rediscovered in a Dublin dining room in the 1990s. Be sure to check out the wings dedicated to Irish artists like Jack B. Yeats as well. A helpful insider tip is to take advantage of the free guided tours, which are offered regularly, to get the most out of your visit. Afterward, you can relax in the Gallery Café or browse the well-regarded shop.
