The construction of the fortified magnate residence, which was almost a copy of the Kielce palace of the Kraków bishops, is generally attributed to Jan Aleksander Tarło, the voivode of Sandomierz and Lublin. This aristocrat from Lesser Poland, patron of the arts, writer and diplomat married Princess Anna Czartoryska in 1653 and the foundation of the new residence may have been connected with this event. The following anecdote provides a slightly different reason for the construction of the palace. At a reception organised by the Kraków bishop Jakub Zadzik in his Kielce residence, the proud host contemptuously refused the voivode's invitation, adding with his innate modesty: "I don't go to cottages". The offended Tarło retorted: "I therefore invite your Excellency to Piekoszów in two years, to the same palace that you have here, your Excellency". Two years later, a building built strictly according to Kielce dimensions was erected in Piekoszów.
The palace was built in the years 1645-50. According to tradition, it cost the founder as much as 30 villages from his estate. Tarło also ordered a small palace to be built near the new residence, which was to be a name-day gift for his wife. Another local legend is associated with this apartment, as if in the middle of summer, a capricious housewife requested to be taken to him by sleigh. Under the pressure of her lamentations, her husband finally gave up and ordered the road to be salted. Piekoszów remained in the hands of the Tarłos until 1842, being inhabited throughout the time. Later, it changed owners several times. In the mid-19th century, the palace burned down and was never rebuilt.
To this day, all that remains of the Tarłos' former seat is a roofless, picturesque ruin with a well-preserved internal division. The building is publicly accessible, which clearly does not serve it well. Its interior serves as a garbage dump, there are also traces of bonfires and a lot of human excrement. It's a pity that no one is taking care of this beautiful monument. In place of the former garden now grows grain.
