Zamość Fortress

Zamość Fortress is a set of fortifications constructed together with the city of Zamość (southeastern Poland). It was built between 1579 and 1618, and the construction was initiated by Chancellor and Hetman Jan Zamoyski. It was one of the biggest fortresses of the Polish–Lithuanian Commonwealth, built so solidly that it was able to resist the attacks of both the Cossacks and the Swedes during the Deluge. It was taken down in 1866, although fragments survive. Altogether, the fortress went through six sieges, with the first one taking place in 1648, during the Khmelnytsky Uprising. Eight years later it was surrounded by the Swedes, who came there again in 1703, then, in 1809, by the army of the Duchy of Warsaw, which captured it from the Austrians. The longest one was the siege of Zamość of 1813, when the Polish garrison for 8 months defended the fortress from the Russians. The last siege took place during the November Uprising, when Zamość was the last point of Polish defence which fell to the Russians.
