250 years of TU Clausthal: A celebration for Lower Saxony's flagship
On June 21, 2025, the Clausthal University of Technology celebrated its impressive 250th birthday with a large ceremony that took place in the historic Aula academica, a domed building from 1927. Prime Minister Olaf Lies (SPD) honored the university as a “flagship of Lower Saxony” and emphasized the university’s role in the areas of research and training. The auditorium is one of the few examples of university architecture from the Weimar Republic and offers a venerable setting for this anniversary.
The Clausthal University of Technology, highly popular with students and recognizable for its practice-oriented approach, is considered a leading institution in the fields of mining, geosciences and engineering. Particularly noteworthy is her commitment to water management, exemplified by projects to ensure water quality in the Harz Mountains. With its position as the highest university in Lower Saxony and the largest employer in the Harz region, it plays a central role in economic development and the educational landscape.
A look into history
Founded in 1775 as the “Clausthal mining training center”, the university laid the foundation for the training of workers and civil servants in the mining industry in the Upper Harz. The development from a mountain school to a renowned mining academy, which enjoyed an international reputation in 1864, is remarkable. In 1968 it received the title of Clausthal University of Technology, evidence of its constant development and adaptation to the needs of the modern education market.
With the anniversary motto “Traditionally Innovative,” the celebrations, which will take place from September 2024 to 2025, will focus on the future developments of the university, its research priorities and new teaching formats supported by digital media. In the 2023/2024 winter semester, around 2,800 students from over 100 countries are studying at Clausthal University of Technology, which illustrates the university's international orientation and appeal.
Festivities and views
The anniversary celebrations include a week of celebrations from June 15 to 22, 2025, during which numerous scientific, cultural and sporting events are planned. A special highlight is the publication of a special stamp issued by the Ministry of Finance in Berlin to mark the anniversary. In addition, a Harzer Wandernadel stamp box will be set up in front of the university in order to promote hiking tourism.
In recent years, Clausthal University of Technology has expanded its training offerings and launched various scientific and engineering degree programs. There is currently a particular focus on the circular economy, supported by funding of 11 million euros from the state of Lower Saxony. The university thus ensures that it will remain a significant player in education and applied research in the future.
Overall, the Clausthal University of Technology is not only an institution with a rich tradition, but also a place full of innovations that will further advance the state of Lower Saxony. The future looks promising and we can be excited to see what developments await us in the coming years.
