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.

Norsk Folkemuseum is an extensive open-air museum at Bygdøy displaying more than 150 traditional buildings from all around Norway, including the impressive Gol Stave Church from around 1200. Craft demonstration, animal feeding and horse and carriage riding are among the many activities available daily through the summer. An indoor exhibition showcases traditional handicraft items, national costumes, and folk art, and offers exceptional insight into Sami history and culture.

A cemetery of historical importance and essentially an open-air museum of Cuba's past, Necrópolis Cristóbal Colón is the final resting place of many prominent Cuban figures and notable families (pick up a map at the entrance to guide you along). The cemetery's best-known resident, the Milagrosa, gathers thousands of pilgrims annually for the miraculous events surrounding her past exhumation, and is believed by Catholics to have supernatural wish-granting powers.

The Botanical Garden of the Heinrich-Heine University is situated in the south of Düsseldorf at the Himmelgeister Rheinbogen (bend in the Rhine). As a research facility, it is not only dedicated to research and teaching, but also open to visitors throughout the year and offers a wide range of events including exhibitions, expert guided tours and lectures.
