In Dagstuhl (being a district of the town of Wadern, Merzig-Wadern county, Saarland, Germany) there is a computer science research center. It is located in a historic country house Schloss Dagstuhl (Dagstuhl Castle), together with modern purpose-built buildings connected by an enclosed footbridge.
The Leibniz-Zentrum für Informatik (LZI, Leibniz Center for Informatics) was established at the Schloss in 1990. The center is managed as a non-profit organization, and financed by national funds. It receives scientific support by a variety of German and foreign research institutions. Until April 2008 the name of the center was: International Conference and Research Center for Computer Science (German: Internationales Begegnungs- und Forschungszentrum für Informatik (IBFI)).
Dagstuhl supports computer science by organizing high ranked seminars on hot topics in informatics. The Dagstuhl seminars which are established after review and approval by the Scientific Directorate bring together personally invited scientists from academia and industry from all over the world to discuss their newest ideas and problems. As part of the Dagstuhl seminars, the center hosts summer schools, group retreats, and other scientific conferences, all discussing informatics. Every year about 3,500 scientists stay in Dagstuhl for about 100 conferences and workshops.
Following the model of the mathematical center at Oberwolfach, the center is installed in a somewhat remote and relaxed location in the countryside. The number of participants is limited to enable discussion and by the available housing capacity. The stay is full-board; participants are accommodated in the original house or in the modern annex, and have all their meals at the center. Seminars are usually held for a weekly period: participants arrive on Sunday evening and depart on Friday evening or Saturday morning. One, sometimes two seminars, and other small meetings are held simultaneously.
Dagstuhl's computer science library, has over 50,000 books and other media, among them a full set of Springer-Verlag's Lecture Notes in Computer Science (LNCS) series and electronic access to many computer science journals.
