Modlin

Modlin is a locality in Nowy Dwór Mazowiecki County, Masovian Voivodeship, in east-central Poland. It forms part of the town of Nowy Dwór Mazowiecki and is best known for the Modlin Fortress (Twierdza Modlin), a large 19th‑century fortification complex built by the Russian Empire to defend the approaches to Warsaw. The fortress occupies a strategic position near the confluence of the Narew and Vistula rivers and was developed as part of the Warsaw Fortress system.

Historically, Modlin has been associated with military activity in the 20th century. It played a role during the Polish‑Soviet War and, in 1939, during the German invasion of Poland, when Polish forces defended the fortifications against German attacks before withdrawing.

Today the fortress is largely preserved and operates as a historical site and museum complex, attracting visitors interested in military architecture and history. In addition to its fortress heritage, Modlin hosts the Warsaw-Modlin Airport, a secondary airport for the Warsaw metropolitan area, located nearby and serving passenger and cargo flights.

Transport connections include road and rail links to Warsaw and the broader region, enabling access to the fortress and surrounding districts. The area also contains residential communities and small-scale industry that benefit from its transport links and tourism related to the fortress and the airport.
