The middle window (slightly wider than the others) on the first floor of the façade is a remnant of the eighteenth century main entrance door, approached by flights of stone steps.
To the west of the palace a few old buildings the farm remain; and the granary from the late eighteenth century was converted into a cinema.
A field hospital, built in the second half of the nineteenth century by the tsarist army and located south of the palace, was demolished in 2001.
Also preserved is an eighteenth-century statue of St. John of Nepomuk, now in the hospital; it probably originally stood on a circular island in the ornamental pond on the north side of the palace.
From the sources it is known among others that Felix Słupecki corresponded with the Dutch Protestant jurist Hugo de Groot (Grotius) who, as an Arminian, was involved on the other side of the Calvinist–Arminian debate.
Słupecki's extensive library contained a number of theological works, and he founded a Reformed Church school in Opole Lubelskie in 1598, with Krzysztof Kraiński [pl] as its first head.
[1] The palace was rebuilt in the Baroque style in the years 1737-1743 for Jan Tarło, the voivode of Lublin Voivodeship, under the direction of Tylman of Gameren, the architect of the court in Puławy.
The Piarists opened the first vocational school of craft in Poland in 1761 in Opole, based on modern principles of teaching.
Jan Tarłó's widow, Sophia Krasinski Lubomirska, created a park around the palace and continued to enlarge the library and art collection.
[4]The house was acquired in 1754 by Prince Antoni Lubomirski, and remodelled between 1766 and 1773 by (among others) Domenico Merlini and the royal architect, Jacob Fontana.
[8] The nearby palace in Puławy belonging to Adam Kazimierz Czartoryski was plundered utterly and burnt by the Russians for his part in the uprising.
[5][10] In 1854 she disposed of (or sold) the house and its contents to the Russian general Ivan Paskyévich, the Namestnik of the Kingdom of Poland since 1831.
[citation needed] After 1854 the Lubomirski palace was converted into a Russian military barracks, undergoing a severe redesign which included the loss of the mansard roof and the removal of the balustrades and tympanums; the third storey was heightened.
