Of all the Belgian cities I visited, Antwerp made the least impression on me. Maybe it was the fair in the city center that made sightseeing difficult, the confusing buildings of the Grote Markt, the fatigue of the journey, or the bad weather. I more than made up for it by admiring the masterpieces of the old masters in the Royal Museum of Fine Arts. Another highlight was a visit to the Diamond Museum, for the processing of which Antwerp is famous, being the undisputed capital of the world's diamond trade.
