Gostynin, the old Mazovian town, a capital of the region, is situated on the border of "Kotlina Plocka" and "Rownina Kutnowska" and on the Skrwa Lewa River. The town is surrounded by beautiful forests, lakes. Some of them are regarded as the Nature Parks, which serve as "green lungs" for the whole Mazovian Region, and a perfect place for relax. The name "Gostynin" appeared for the first time in 1136 in a form of Gostyna or Gostynio, in 1279 it had the present form though in 1329 it was Gostynensis, and in 1462 Gostynino or Goszczymino (1473). The name night have originated from Goscimir (the town owned by Goscimir), or from the noun "goscie" which means visitors (according to Trojanowski).

 The orginal town of Gostynin was founded in the 13 thc by Konrad Mazowiecki on so-called "Lysa Gora" not far from Kociol Lake (at present the territory of the Roman-Catholic graveyard). A church under the invocation of St. Jacob was built nearby (now the graveyard chapel). In the 70s of the 14 thc a new castle is built (Novum castrum), and on the 8th march 1382  Prince Siemowit  IV gives city rights to Gostynin. In the same year so-called Newn Town appears (Nova civitas).

These are the real begginings of the town of Gostynin Since that time the town has been the centre of local authorities. In 1462 the Gostynin Region was joined to Poland. In 1476 the region became the part of the Rawa Voievodship, and at that  time it was subdivided into two smaller units: Gostynin and Gąbin.

In 1564 there were 1600 inhabitant in Gostynin and 256 houses, while in Gąbin 2100 inhabitants and 354 houses (but Gąbin had never had a castle). After 1795 both units were a part of the Prussian department of Plock, during the time of "Ksigstwo Warszawskie" a part of the Warsaw department. After Polish Kingdom had been established the Gostynin Region was a part of the Mazovian Voievodship but .then Gąbin was the administrative centre, because Gostynin was destroyed by fire on the 28th May 1809. In 1845 the administrative centre was moved to Kutno by Russin officials. In 1866, after 60 years, the Gostynin department was re-established, and Gostynin was ance again the capital. From 1915-1919 the town lost the city rights for a short time During the time of so-called "Second Rzeczpospolita" a department was established with Gostynin as its centre, and from 1939 to 1945 the region belonged to Germany.

 After World War II the Gostynin department was re-established and since 1975 it has been a part of the Plock Voievod-ship. The crest of the town of Gostynin belongs to so-called archictural crests and it appeared after 1382 the form was preserved (though with some changes) untill now The crest is formed by three white towers joined by a red wall.
