Home also to ICALP 1996, the Heinz Nixdorf MuseumsForum hosts both the world's largest computer museum, as well as modern conference facilities. The museum's 6,000 square metre exhibition space follows 5,000 years of information technology history, from early writing to calculating machines to modern computer technology. Special exhibitions and series of lectures complement the main exhibition. The adjacent Heinz Nixdorf Institute, founded in 1989 from the estate of Heinz Nixdorf, together with the state of North Rhine-Westphalia and Paderborn University, is a world-class interdisciplinary research centre studying application-oriented areas of computer science and engineering, with ties to the humanities and social sciences

The Heinz Nixdorf Institut (HNI) is a research institute that focuses on computer science and its applications in engineering, natural sciences, and other fields. Established in 1989, HNI is named after Heinz Nixdorf, the founder of the computer company Nixdorf Computer AG. The institute conducts research in a wide range of areas, including software engineering, artificial intelligence, robotics, and human-computer interaction.

Paderborn is a walkable, green city with a rich history of over 1,200 years, contraposed by its strong tradition in computer science research and tech company development. Founded in 795 by Charlemagne, its famous inhabitants include Friedrich Sertürner, who discovered morphine in 1804, Karl Weierstraß, who attended its grammar school Theodoranium (one of the 10 oldest schools in the world, and which still stands today in the city center), and most recently, Heinz Nixdorf, namesake of the Heinz Nixdorf MuseumsForum and founder of Nixdorf Computer AG. The city center is home to centuries-old sights, including the Romanesque-Gothic cathedral with its 92m tower, dating originally from the 8^th century, and the city's town hall from 1620 in the Weser Renaissance style. Nearby lies the namesake of the city, approximately 200 springs from which the Pader river takes shape, nestled in the picturesque “Paderquellgebiet” park.

Roughly 30 mins walk from the conference center lies Schloß Neuhaus, the former residence of the Paderborn prince bishops. This moated palace with its lovely Baroque Garden is well worth visiting, and is pictured in the Modern Computer Algebra textbook of von zur Gathen and Gerhard. For those seeking green space in nature, the "Fischteichen" is 15 minutes by foot from the conference, featuring kilometers of shaded walking paths, ponds, and a tree climbing park.
