Karol Podczaszynski (Lithuanian: Karolis Podcašinskis) (7 November 1790 – 19 April 1860) was a Polish architect, a representative of the neoclassical architecture and a professor of the Imperial University of Vilna, as well as one of the pioneers of industrial design.
He was born on 7 November 1790 in the village of Zyrmuny near Lida, in what is now the Hrodna Voblast of Belarus.
He graduated from the prestigious Polish Liceum Krzemienieckie and the Imperial University of Vilna.
Between 1814 and 1816 he continued his studies on architecture in St.
Petersburg, where he became the first Pole on the Imperial Academy of Arts.
Between 1817 and 1819 he also travelled to Western European countries, visiting Königsberg, Danzig, Berlin, Paris, Naples, Venice and Vienna before returning to Cracow.
Upon his return to Vilnius he was offered a chair of architecture, which he accepted.
Among his most notable architectural works are the refurbishment of the interior of the Vilna University (1802-1804), including the Aula's interior, Evangelical Reformers' Church (1829-1835) and the neoclassical Jan Sniadecki's manor in Jašiunai (reconstructed between 1824 and 1828).
Yet another of his major works was the neo-Palladian Tusculanum manor (in modern Žirmunai, Vilnius), completed in 1825.
The entire Žirmunai microdistrict in Vilnius was named after his native village, a part of the Polish-Lithuanian Commonwealth at the time of his birth.
As a noted architect, Podczaszynski also supervised a number of other projects, among them the reconstruction of the Palace of Governors in Vilnius, carried out by Vasily Stasov.
In modern times the palace serves as the seat of the President of Lithuania.
Podczaszynski has also reconstructed the Orthodox Cathedral of the Theotokos into the Anatomicum of his alma mater (1822).
Finally, between 1836 and 1838 he designed the interior design of three chapels of the St.
Wladyslaw and Stanislaw Cathedral of Vilna.
In 1839, Karol Podczaszynski took the first known daguerreotype in present-day Lithuania.As a theoretician, Podczaszynski authored works on architecture and industrial design.
Karol Podczaszynski died on 19 April 1860 in Vilnius and was interred in Rasos Cemetery.
Karol's son, Boleslaw Podczaszynski also became a noted architect.
