"

Riga Polytechnicum was first established in 1862 and was the first polytechnical institute in Imperial Russia. It offered degrees in agriculture, chemistry, engineering, mechanics, trade and architecture, with education in German. In 1896, it was renamed Riga Polytechnical Institute and the language of instruction was changed to Russian. The establishment of a faculty of architecture at the Polytechnicum in 1869 was instrumental in providing Riga with a group of locally trained architects, with consequences for the development of the characteristic Art Nouveau architecture in Riga.[1]
