Saarbrücken has plenty to offer to the lovers of architecture, and one unmissable landmark is the city's town hall, built at the turn of the 20th century in neo-Gothic style and designed by Georg Von Hauberrisser, whose works also include the town hall in Munich.

Völklinger Hütte, one of the world's largest iron works spreading across six hectares, was established in 1873, and has remained remarkably intact during its operation spanning the next hundred years. Today, as a UNESCO World Heritage Site, it functions as a museum and science centre, offering interesting insight into the industry's history.

In the heart of the austere and monumental Victorian grandeur of Adelaide's official buildings, you will find the Art Gallery of South Australia. It houses nearly 45,000 works of art spanning 2000 years. From paintings, prints and drawings, photographs and videos to sculpture, textiles, ceramics, jewellery and furniture. It's a vast collection, which covers Aboriginal art, colonial and modern Australian, European art, and much more.

The Kunstsammlung Nordrhein-Westfalen presents a demanding and variegated exhibition program at three locations: at the K20 Grabbeplatz, at the K21 Ständehaus and at the Schmela Haus. Around a half-century ago, in August of 1961, the regional government of North Rhine-Westphalia established the Foundation of the Kunstsammlung Nordrhein-Westfalen. The purchase of 88 works by artist Paul Klee was the “opening salvo.” Since then, the Kunstsammlung has become one of the most recognised art museums worldwide, with a collection which ranges from Classical Modernism to American Pop Art and major contemporary works.
