Head up Rue Royale towards the grand neoclassical 19th-century Church of Madeleine, built in the style of a Roman temple, with 52 65-foot Corinthian columns bearing the weight of the roof. Pop in if you have time – there is a beautiful frescoed half dome over the altar – then stop off at Ladurée, at number 16, and pick up a box of pastel-colored macaroons. The little round cakes, which come in all manner of shades, from frothy pink to pistachio green, are made from almonds, eggs and sugar, with a layer of smooth ganache between two squishy shells. Although the patisserie dates back to 1862, it now has branches all over the world (including two in Manhattan and one in Miami), and the adjacent salon is a charming place to enjoy a cup of tea. Open 8:30 AM to 7:30 PM Mon-Thurs, until 8:00 PM Fri-Sat, 10:00 AM to 7:00 PM Sun.
