About 1859 the building of the present palace was finished. Its founder was 13th Ordynat (6th from Wielopolski family), margrave Aleksander Wielopolski (1803 - 1877). Late classical palace designed by Henryk Marconi was built mainly to hold a large estate library, and the collection took over from Konstanty Świdziński, friend of the margrave, as well.
A central projection of first floor is formed by four-column porch, which contains the main entrance to the palace. Its equivalent on second floor is a terrace, which is crowned by attic with four classical statues (Germanik, Ceres, Minerwa and Achilles) made by Andrzej Pruszyński, sculptor from Warsaw. Above the terrace, there are two crests, Półkozic (of the Świdzińskis family) on the left, and Jastrzębiec (of the Myszkowskis family) - on the right. Starykoń, the Wielopolskis family crest is located on the other side of the palace.
The east (right) side of the palace was used as the place of welcoming the visitors. In the former Hunting Room (the Parlour) there are four portrait medallions preserved, with the likenesses of the palace owners. There were sculpted by Andrzej Pruszyński. Next to this room, there is a round palace chapel.
In the Ball-room, with original coffers, there were scenes to "Przedwiośnie" (directed by Filip Bajon) shot in year 2000.
The office part of the palace consists of the Library Room and the Private Study of margrave Wielopolski. Only the book case and the desk preserved to the present. On the second floor, there were bedrooms.
The palace is surrounded by the english park, with a lot of monumental trees, for example the London Plane (Platanus x hispanica Münchh.), Ginkgo biloba, lime trees. In the park, there is also a chapel preserved, designed by Marconi, which imitates the garden pavillions of Książ Wielki castle.
