The Grand Ducal Palace, the official residence of the Grand Duke of Luxembourg, is a historic and majestic landmark in Luxembourg City. Its interior is exclusively accessible via guided tours, typically offered during a limited summer period (July to early September), making advance booking highly recommended due to high demand. Tours usually last 45-60 minutes and cost approximately €15 for adults, with proceeds often benefiting local charities. While the interior is restricted to guided visits, the stunning facade and the ceremonial changing of the guard can be observed year-round by solo visitors from the outside. The palace is centrally located and easily accessible on foot, though visitors with mobility concerns should confirm specific accessibility accommodations for interior tours at the time of booking.
