Once you've finished ogling the Old Town and Ostrów Tumski, there's a third essential district of this fine city that visitors will be poorer heading home without having seen. Just east of the city centre lie a clutch of attractions surrounding the historic Centennial Exhibition Complex, including Centennial Hall - Wrocław's only UNESCO site, the country's oldest zoo, the tranquil Japanese Garden, the tourist-luring Pergola Fountain and the newly renovated Four Dome Pavilion. Intended as a city showpiece since its creation, the area east of the Odra long held a somewhat lukewarm public standing thanks to dubious historical connotations and debatable aesthetic appeal; however recent renovations, the UNESCO nod and the addition of the magnificent multimedia fountain (operating May-October) have made it a favourite place of the locals and cemented its place as a Wrocław must-see.
