As it is told by the Pustan Rascals (Betyár)...

"Francisco Rákóczi II., a reigning prince (chief) of the early 18th century, during one of the sieges of Kurutz freedom fights set up his camp in the place of present Sarlóspuszta in 1710. It was here that he met a beautiful woman, Sára Sarló, whom he fell in love with for the first glance.

The Transylvanian nobleman had this mansion built as a lovenest for the nice woman and named it after her as the Pusta of SarlóSára (today Sarlóspuszta). During the years of his exile in Turkey Sarlóspuszta became the most important refuge of hiding freedom fighters and also of pustan rascals from the neighbourhood, who, not just found a plate of hot meal there, but hide and protection, as well.

As it is explained by historians...

Tatárszentgyörgy is the Southernmost settlement of Comitat Pest. Its most ancient archeological remains date back to the Bronze Age. The settlement at its present name occur first in 1507 in records. The village had been abandoned during the fifteen-year-war. The resettlement and repopulation of it took place gradually until the end of the 18th century.


Tatárszentgyörgy Puszta, which was abandoned during Turkish times, is possessed in the beginning of the 18th century by two widespread noble families, with a past dating back long in time, the Kubinyi family of Felsőkubin and Nagyolasz and the Máriássy family of Márkusfalva and Batizfalva. Graf Antal Grassalkovich (I.) of Gyarak bought both parts of their land and he became the owner of the whole pusta by 1734. The manor with the mansion that is Sarlósárpuszta, belonging to Tatárszentgyörgy, became his possession in 1758 also from the Kubinyi family. Repopulating of the settlement had been started by Antal I. in 1751, and was completed by Antal II., his son, in the 1770-ies.
According to some sources the Grassalkovich castle of Sarlóspuszta had been built by Antal I. around 1760. This must be a mistake though, because a list of the Graf set up by him, was found in the National Archives from 1771, in which there is the description of the constructions in his estates together with the details of the buildings. Not any castle of Tatárszentgyörgy is mentioned in these (but there is for example a large-size sheep stable marked among the records), but according to its style it can be dated to the second half of the 19th century. (At the same time there is an inn mentioned by the Graf which might have been used as the later castle.) There is a hint though in the monography of Pest-Pilis-Solt-Kiskun comitats by Samu Borovszky about a reconstruction in 1858, which had been carried out between 1843 and 1856 by the owner Gábor Török of Várad who followed the previous owner Keglevich Grafs of Buzin.
From 1863 the owners of the estate are the inheritants of Baron Frigyes Bors of Borsod and Csíkszentmihály, then Baron Bela Lipthay of Kisfalud and Lubelle and Mrs Graf Otto Bissingen-Nippenburg.We find the building in the hands of the Muchony family around 1920 and Peter Halász of Gyón is named as the owner from 1931 until 1945. (In these days the mansion was famous for its extremely rich and interesting collection of antlers.)
After the 2nd World War the building was used as a school, later there were apartments in it. From the mid-80-ies there has been an inn in the nicely renovated mansion.
The mansion bears the traces of several reconstructions.
