The KTH Royal Institute of Technology (Swedish: Kungliga Tekniska högskolan, lit. 'Royal Institute of Technology'), abbreviated KTH, is a public research university in Stockholm, Sweden. KTH conducts research and education in engineering and technology and is Sweden's largest technical university. Currently, KTH consists of five schools with four campuses in and around Stockholm.
KTH was established in 1827 as the Teknologiska institutet (Institute of Technology) and had its roots in the Mekaniska skolan (School of Mechanics) that was established in 1798 in Stockholm. But the origin of KTH dates back to the predecessor of the Mekaniska skolan, the Laboratorium mechanicum, which was established in 1697 by the Swedish scientist and innovator Christopher Polhem. The Laboratorium mechanicum combined education technology, a laboratory, and an exhibition space for innovations. In 1877 KTH received its current name, Kungliga Tekniska högskolan (KTH Royal Institute of Technology). The Swedish king, Carl XVI Gustaf, is the patron of KTH.
KTH is ranked 73rd in the world among all universities in the 2024 QS World University Rankings, which is higher than any other university in the nordic countries.
