One of Dublin's most exquisite, yet also most underrated, architectural landmarks, the Marino Casino (the name means "little house by the sea," and the building overlooks Dublin Harbour) is a small-scale, Palladian-style Greek temple, built between 1762 and 1771 from a plan by Sir William Chambers. Often compared to the Petit Trianon at Versailles, it was commissioned by the great Irish grandee Lord Charlemont as a summerhouse. Inside, highlights are the china-closet boudoir, the huge golden sunset in the ceiling of the main drawing room, and the signs of the zodiac in the ceiling of the bijou library. When you realize that the structure has, in fact, 16 rooms—there are bedrooms upstairs—Sir William's sleight-of-hand is readily apparent: from its exterior, the structure seems to contain only one room. It makes a good stop on the way to Malahide, Howth, or North Bull Island.
