Vyborg Main Post Office, Neoclassical post office in Vyborg, Russia

Vyborg Main Post Office is a neoclassical building with symmetrical stone facades and evenly spaced windows arranged along Krepostnaya Street. The structure follows classical proportions and displays carefully executed architectural details throughout its exterior.

Built between 1912 and 1914 to designs by Jacob Ahrenberg, this was his last project, modelled on Drottningholm Palace near Stockholm. The post office had stood on Yekaterininskaya Street since the mid-18th century; the new building rose as the city centre expanded south-east after the 1861 plan by B. O. Nymalm. Construction cost about 550,000 Finnish marks. On 29 April 1918, White troops shot six postal workers, including writer Kössi Ahmala, in the courtyard.

The facade still carries bilingual signs reading "Почта" and "Poste", a trace of the years from 1890 when the postal service of the Grand Duchy of Finland belonged to the Russian Ministry of Internal Affairs. The building was modelled on Drottningholm Palace near Stockholm, and its three-part plan with an inner courtyard shows neoclassical features.

The main entrance faces Krepostnaya Street, while a side door on the same street once led to the road and waterworks offices. The two-level operations hall is reached by a wide granite staircase. The building still serves its original postal function, so visitors can step inside during opening hours.

Six postal employees, including the writer Kössi Ahmala, were shot in the courtyard on 29 April 1918 after Mannerheim's troops took Vyborg; Ahmala had once carried Lenin's mail from Petrograd. The building was completed in 1914, not 1912, and still serves as a post office.
