The world's first interactive science center devoted to mathematics offers more than 150 activities which playfully explain often complicated mathematical phenomena. Visitors both large and small wander through the exhibits, and before they know it, they're having fun with math. The museum was an immediate hit when it opened its doors in 2002 and now attracts about 150,000 visitors annually. The museum is the vision of its energetic director, Albrecht Beutelspacher, a mathematics professor at Gießen University. The interactive exhibits are developed by both educators and math students. The Mathematikum is open seven days a week and is suitable for children 9 years and older. The new Mini-Mathematikum is designed for children aged 4 - 8.
Considered one of the most important chemistry museums in the world, the Liebig-Museum offers a unique historical insight into one of Germany's greatest scientists - Justus Liebig. Liebig's work laid the foundation for agricultural and organic chemistry, and his innovative teaching methods rank him as one of the greatest chemistry teachers. At the age of 21, Liebig was named professor in Gießen, and today the university is named after him. The museum illustrates how Liebig conducted research during his 28-year tenure and how he developed his teaching methods.

For centuries, the Lahn-Dill region was one of Europe's most important iron ore mining areas. At its highpoint in 1873, there were 115 working mines in the vicinity of Wetzlar. But by the 1920s, the decline of the industry began and the last mine - Fortuna - was closed in 1983. Today, visitors can experience the working environment of miners - 150 meters below the surface - and see how iron was originally mined. The Fortuna Mine in Solms-Oberbiel is open from March to November.
