25 Oktyabrya Street 13b, Tyumen, Regional cultural heritage site in Tyumen, Russia

The House of the Noble Assembly at 25 Oktyabrya Street 13b is a two-storey classicist mansion with a mezzanine and two four-column porticoes. The porticoes stand on massive arcades supporting an entablature with a pediment. Its two equal facades face the Tura River and the city; windows are narrow and lack surrounds, and the facades carry stucco ornament and rusticated arcades.

The building's origins are disputed: one account credits merchant Prasolov with a residence in the first quarter of the 19th century, another merchant Semyon Trusov with construction in the 1840s, and a third attributes the design to architect Malyshev in Tobolsk in the 1820s. In 1869 it became a transit point for exiles, handling up to 15,000 people a year. It was listed as a regional architectural monument by Resolution No. 1327 of 30 August 1960.

The name Narodny Dom (People's House) comes from the free public library for ordinary citizens opened here in the late 19th century, which hosted lectures, musical-literary evenings and literacy classes. In 1911 the city's first sobering-up station, with 30 places, opened in the building; until 1913 it was free and used brine and ammonia. A memorial plaque on the facade recalls the evacuation hospital No. 2475 housed here in 1941–1945.

The building is the official residence of the Tyumen governor, so it is not open to the public as a museum. Visitors can view the restored two-storey classicist facade from 25 Oktyabrya Street and from the bank of the Tura; a memorial plaque marks the 1941–1945 evacuation hospital No. 2475 housed here.

A city legend holds that underground passages run from the former Noble Assembly House to the Tura River. The building also housed Tyumen's first sobering-up station, opened in 1911 for 30 people and free until 1913, where patients were revived with brine and ammonia.
