 Saint Petersburg State Forestry University (often referred to historically as the Forestry Academy or Lesotekhnicheskaya Akademiya). Established in 1803 by decree of Emperor Alexander I as the Practical Forestry School in Tsarskoye Selo. In 1811, it was moved to its current location in the Vyborgsky District of Saint Petersburg, occupying the site of an old English dairy farm. The classical white building shown in the photo is the Main Educational Building. Originally constructed as four separate corps between 1826 and 1833 by architects I.F. Lucchini and A. Nellinger, these were later united into a single complex with a central courtyard in the late 1830s. Lesnoy Park (Lesotekhnicheskiy Universitet), Saint Petersburg, Russia, October 14, 2025
