One of the main tourist attractions in Tatarstan is the island city of Sviyazhsk which is located in the Zelenodolsky district.

A boat is located in the center of the green background, symbolizing shipbuilding which is the main branch of the region's economy.

A hammer is depicted on the sail of the boat as the symbol of one of the leading industrial enterprises of the region - the "Zavod imeni Sergo".

Azure color symbolizes the Volga, and the silver belt means the Moscow-Kazan highway, which passes through Zelenodolsk.

In 1897, the village was renamed as Paratsk or Paratsky Zaton, by which time it had become a place for repair and wintering of river ships sailing along the Volga.

In 1932, according to the Resolution of the All-Russian Central Executive Committee, Zeleny Dol received the status of a city and the name Zelenodolsk.

[11][6][7][12] On January 1, 1948, the district included three village councils: Vasilievsky, Oktyabrsky and Yudinsky, and 24 village councils: Aishinsky, Belo-Bezvodninsky, Bishninsky, Bolshe-Derbyshkinsky, Bolshe-Klyuchinsky, Bolshe-Kulbashsky, Bolshe-Kurguzinsky, Bolshe- Yakinsky, Borisoglebsky, Garinsky, Kadyshevsky, Kindersky, Krasnogorsky, Malo-Klyuchinsky, Nikolsky, Novopolsky, Osinovsky, Osoko-Kovalinsky, Remplersky, Russian-Mari-Kovalinsky, Semiozersky, Sukhoretsky, Urazlinsky and Shigalinsky.

[13][14] The island of Sviyazhsk, located at the confluence of three rivers (Volga, Sviyaga, and Shchuka) is part of the Zelenodolsky district.

By the decree of the Presidium of the All-Russian Central Executive Committee of February 1, 1932, Sviyazhsk was transformed into a rural settlement.

[16] Since 2010, large-scale work on the restoration and reconstruction of sights began on the island within the framework of the "Revival" program of the Republican Fund for the Preservation and Development of Bulgar and Sviyazhsk.

Radik was then replaced by Sergei Batin, who in 2012 became a member of the Federation Council as a representative from the executive body of the Republic of Tatarstan.

The main activity of the enterprise is the construction of ships for both the domestic and foreign markets and the fulfillment of national defense orders.

In 2017, the factory's net profit amounted to 90.5 million rubles with the company provided up to 50% of the revenues of city and district budgets from its contributions alone.

[23][24][25] The Zelenodolsk Plywood and Furniture Factory is controlled by the general director of the Kamaz plant Sergey Kogogin and his brother Alexander.

Dairy and beef cattle breeding are among the primary forms of livestock agriculture in the district along with poultry farming and beekeeping.

Major agricultural investors active in the district are Krasny Vostok Agro and Ak Bars Holding.

For 2020, all the sections of the park are occupied by residents, of which two Promenergo projects and the X5 Retail Group distribution center have been commissioned.

The TASED also includes 220 hectares of the Sviyazhsky multimodal center which 7 billion rubles were attracted from the federal budget for its construction.

[37][38][36][39] In January–June, the total volume of investment in fixed assets of the region, excluding budgetary funds, amounted to 4 billion 11 million rubles.

[27] In 2005, Deputy Prime Minister of Russia Marat Khusnullin proposed a concept for the development of a new microdistrict "Zeleny Dol".

There is a river station in Sviyazhsk, but water communications with the island are carried out only from Kazan, though in winter, there is an ice crossing.

In 2007 the construction of the Sviyazhsky Multimodal Logistics Center (SMMLTs) was initiated which will unite road, rail and river routes passing through the district.

The river Sumka passes through the Raifsky section which flows into the Raifskoye Lake with an area of 30 hectares and a depth of 20 meters.

The park has a large arboretum in which more than 400 species of plants from North America, Western Europe and Asia are collected.

[47][48][49] The Zelenodolsky district is served by 17 medical institutions, 50 feldsher and obstetric hospitals, which employ more than 450 doctors and 2,800 mid-level healthcare workers.

A modern educational and entertainment complex "Kazan Planetarium" and an astropark have been built by expanding on the basis of this observatory.

Local media is represented by the regional newspapers Zelenodolskaya Pravda and Yashel Uzun (Zeleny Dol) which publish in Russian and Tatar.
