Zvenigorodskaya is a station on the Saint Petersburg Metro. It is located between the Sadovaya and Obvodny Kanal stations on the Frunzensko–Primorskaya Line. The station was opened on December 20, 2008, one of the first on the new line. It is connected by foot passages to the Pushkinskaya station, which serves the Kirovsko–Vyborgskaya Line. At the time of its opening, Zvenigorodskaya lacked an independent surface exit; all traffic had to go through Pushkinskaya. Escalators and a surface lobby were added later.
Buses: 225, 262, 290.
Trolleybuses: 3, 8, 15, 17.
Trams: 16.
According to initial data from the Saint Petersburg Metro press service,[1] a concourse building was planned by architect Alexander Konstantinov, and described as a two-storey building with a portico,[2] harmoniously integrated into the architectural ensemble of the former Semyonovsky regiment barracks.[3]
A specially constructed building was planned to be situated between houses No. 1 and No. 3 on Zvenigorodskaya Street. Originally, it was intended to resemble the appearance of the Semyonovsky Regiment barracks, the ground floor to house the concourse, while the second floor was designated for Saint Petersburg Metro services. Eventually, a five-storey shopping mall designed by the "Adamant" company was authorised.[4]
Zvenigorodskaya was originally designed as a deep column station. However, due to a long construction break, it was decided to replace part of the column complex with a wall. This decision helped prevent the displacement of already established columns. The lateral tunnels of the station have an increased diameter of 9.8 meters (32 feet) compared to typical columned stations in Russia. The average hall has a typical distance between the axes of columns of 3.8 meters (12 feet) in the longitudinal direction and 8 meters (26 feet) in the cross-section.
The original project of the station was executed by Russian architect Alexander Konstantinov.[5] However, after its opening, it was declared that the authors of the project were a group of architects from the Open Society "Lenmetrogiprotrans," led by N. V. Romashkin-Timanov. The team included N. V. Romashkin-Timanov, Yu. V. Eechko, D. A. Bojtsov, and N. A. Vinogradova.[6]
The decoration of the underground part of the station also reflects themes related to the Semyonovsky Regiment, whose barracks were located around the station's surface exit. The floor is constructed from green granite, Rakhi Green (India), with color inserts and trim made from red granite, Imperial Red (India). The walls are clad in Koelga marble, Kashin granite, and dark green marble, Indiana Green (India). The selection of the supplier and the stones from India was made by the leading natural stone expert, Vladimir Shestakov.
The station features mosaic panels made of smalt depicting the first soldiers of the Semyonovsky regiment who served during the reign of Peter the Great. These panels were crafted by the Russian Academy of Arts,[7] with the artist Alexander Bystrov as the creator.[8]
The station's illumination is provided by fixtures installed at the tops of the columns.
The Zvenigorodskaya station on the Frunzensko-Primorskaya Line and the Pushkinskaya station on the Kirovsko-Vyborgskaya Line are connected by a foot tunnel. This is the first transfer foot tunnel in the Saint Petersburg Metro, to be constructed after a long break. The previous transfer tunnel was built 18 years earlier at the Sadovaya station and opened in December 1991. The design of the new tunnel incorporated innovative techniques for the underground railway system.
At Zvenigorodskaya station, the central part of the average hall is separated from the platforms by walls. This design has allowed the central part to be elevated above the station floor, with two longitudinal escalators leading to it. Above, in the transition area, ladders lead to three corridors that connect to a small hall.
The tunneling was carried out simultaneously from this hall to both stations.[9] From the hall leading to Pushkinskaya, there are two corridors that end with ladders. These ladders replaced a pylon and two passages adjacent to it.
During the construction of the transition, two chandeliers that illuminated the ceiling of the Pushkinskaya station platform were removed. These chandeliers were subsequently installed in the hall where the transition corridors lead.

Several construction organizations worked on the Zvenigorodskaya station:
The construction of the station was completed in three stages:
In 1990, projects for the stations, including Zvenigorodskaya, were developed. Rough tunnels for train movement were completed. However, construction was subsequently halted, and the building was left in a preserved state.
The station and the underground transfer were built in 2007–2008. In July 2007, the arches and walls separating the central hall from the platforms were constructed.
In January 2008, a significant number of problems were resolved:
On November 27, 2008, the mosaic panel was fully completed.[11]
From December 20, 2008, to March 7, 2009, train service from the station was operated in shuttle mode until the opening of Spasskaya station and the division of the Pravoberejnaya line.[15]
The direct surface exit was constructed starting in 2007. In July 2007, work began on the construction of the lobby and the inclined escalator.
In January 2008, work began in several areas:
In August 2009, work was completed on the installation of all four escalators. Following this, the installation of the ferro-concrete walls for the ground floor began. Above the station, four floors of a shopping center were to be constructed.[16]
