Fodor's Expert Review Palais Grand-Ducal

The city's finest building dates from the 16th century. Its elaborate facade shows a Flemish Renaissance influence, with ornate balconies and a symmetrical exterior, and it was formerly the home to the Grand Ducal royal family. It is now mainly used for business and entertaining, though in July and August it opens its doors to visitors, offering the chance to explore its extensive art collection, which was dispersed during World War II before being returned, and the Hall of Kings where foreign envoys are officially received.
