Here's a chance to find out how the other half lived in the 18th-Century. The Museum of Decorative Arts is housed in an exquisite aristocratic abode on Portas do Sol square, overlooking the narrow lanes of Lisbon's medieval Alfama neighborhood. The cool interior is packed with four centuries worth of Portuguese antiques collected by banker and art lover Ricardo do Espírito Santo Silva. It's laid out like a private home of the 1700s; visitors will be wowed by the collections of porcelain, crystal, silverware, and gilded furniture, and by the views across the city and the river below from the palace windows. The foundation that runs the museum also maintains workshops next door dedicated to restoration work and the preservation of ancient craft traditions from cabinetmaking to gold beating, book binding to embroidery.
