William Square, Our Valley Travel Guide

William Square, or Place Guillaume II, is the beating heart of Luxembourg City—an expansive open space where the old and new converge amid the storied streets of Ville Haute. Historically, the site began as a Franciscan monastery cloister, lending the area an atmosphere of monastic calm even centuries later. In 1829, the monastery was demolished to create a stately public square, its namesake derived from Grand Duke William II, who also served as King of the Netherlands and is immortalized at the northern edge by a bronze equestrian statue. Dominating one side of William Square is the Hôtel de Ville, the city’s imposing neoclassical town hall with stately columns and a proud flag flying above its portico. The square itself transforms several times a week: on Wednesdays and Saturdays, the plaza bursts into color and aroma with local produce markets and flower stalls, creating a lively contrast with its grand architectural backdrop. The rhythm of modern city life is palpable here, with locals pausing at café terraces and friends meeting beneath the statue’s steady gaze.Visitors will find themselves conveniently positioned amid a constellation of Luxembourg highlights—the Cathedral of Notre Dame is only steps away, and from the plaza’s southern end, winding streets spill into the city’s renowned shopping district. Throughout the year, William Square hosts festivals, concerts, and parades. In winter, it becomes a magical stage for a Christmas market, twinkling with festive lights. The square balances grandeur and accessibility, resulting in a place that feels regal yet warmly intimate—a rare quality in a national capital. Its central location and free open access make it an essential orientation point and gathering place for both first-time visitors and returning Luxembourgers.
