It is one of the oldest settlements in southern Mazowsze. In the 11th and 12th centuries a castellan settlement existed in Grójec which was located in the place of today’s parish church. It was most probably preceded with the settlement situated in the valley of the Wola Worowska River.

In the 12th century a local parish and seat of archdeaconry were established here. There was a congregation of the canons near the church. The oldest information about Grójec dates back to the year 1234 (in the period of Konrad I Mazowiecki). In the middle of the 13th century the archdeaconry was moved to Czersk. The importance of Grójec was weakend significantly as a result of actions undertaken by Duke Konrad I who marked off a castellany in Czersk from the lands of Grójec castellany, which had previously included south-east Mazowsze.

In 1419 Duke Janusz I granted municipal rights to the settlement under the Chełm Law. These municipal privileges were extended by: Mazovian Duke Bolesław IV and Kings Zygmunt I Stary and Zygmunt August. In the 15th and 16th centuries the town was booming. The town hall was built and the streets were cobbled. After the incorporation of Mazowsze to the Crown in 1526 Grójec became a royal city and a center of the starosty sine iurisdictione within the new Mazowieckie Province. In 1564 Grójec consisted of 210 houses for about 1,000 inhabitants. The local craftsmen specialized in slaughter, beer and vodka production and manufacture of lute strings made of sheep bowels.

The Swedish Deluge in 1655-1660 brought a complete destruction of the town. In 1660 there were only 16 houses and 2 craftsmen in Grójec. Throughout the next one and a half century the town was experiencing an economic and demographic stagnation.

Following the Third Partition of Poland in 1795, Grójec was under the Prussian dominion and the center of the Czersk County in the Province of South Prussia.

In 1797 the town numbered 78 houses. It became a part of the The Duchy of Warsaw, (Warsaw department) in 1807 and eight years later of the The Kingdom of Poland (Mazowieckie Province). In 1867 the tsarist authorities established Grójec County.

It was not until the 19th century that Grójec began to grow intensively. Building the beaten tracks connecting the town with Warsaw and other adjacent towns as well as the opening of narrow-gauge railway with Warsaw (1898) and Nowe Miasto on the Pilica River (1916) resulted in a revival of a trade exchange. Also, small food industry enterprises and brickyards producing building materials for the capital city market started to appear.

After Poland regained its independence, Grójec was a county town in the Warsaw Province.

In October 1939 the city was incorporated into the Warsaw District of the General Government. During World War II in the vicinity of Grójec partisan units were fighting in close order with the Germans.

At present Grójec remains a center of fruit and vegetable farming on a scale reaching the whole European market. In 1975 the city became part of the Radomskie Province, and after the government-administrative reform it is the seat of the authorities of Grójec County in Mazowsze Province.
