The National Gallery of Ireland was established by an Act of Parliament in 1854. Today, the collection includes over 2,500 paintings and almost 10,000 other works of Irish and European art, including watercolours, drawings, prints, and sculptures.

Dominating the city skyline, you can’t fail to notice it: the Imperial Castle. At the time of the Holy Roman Empire, the castle was occasionally home to each of the emperors, and in the Middle Ages, it was one of the most important royal palaces. The sights here include the new castle museum, the palace with the emperor’s living quarters, the Romanesque Double Chapel, the Deep Well and the Sinwell Tower. The neighbouring garden is a must-see too. It might be small, but it’s a welcome contrast to the hustle and bustle of the city and is popular with residents too. The castle's garden is open from April to October.

The Longji terrace fields date from the Ming Dynasty, about 500 years ago. Winding from the base up to the top, it divides the mountain into layers. Sights alter here as the season changes: water glittering in the sun in spring, green rice shoots in summer, golden rice in fall and silvery frost in winter. It is advised to stay overnight so that you can see the sunrise and sunset, which should not be missed.
