The Passeggiata Margherita is Viareggio's seafront promenade — a wide, tree-lined boulevard running along the beach, flanked by the bathing establishments, shops, and cafés that give the town its character. The promenade dates to the early twentieth century and is lined with fine examples of Liberty-style (Italian Art Nouveau) architecture: ornate wooden pavilions, wrought-iron balconies, and tiled facades painted in soft yellows and blues. The Gran Caffè Margherita, a restored wooden pavilion at the northern end, is the most celebrated of these — a listed monument and the best vantage point for appreciating the style. Walking the full length of the promenade at dusk, when the beach establishments put out their lights and the Versilian marble mountains glow behind the town, is one of the better free pleasures on the Tuscan coast.
