The lime avenue leading from the square to the main gate with an arched gable and the gatekeeper's house leads to the Great Courtyard of Průhonice Park. The Renaissance-style entrance gate is replaced on the inner side by the motifs of a timbered folk building with a lomenica and a balcony.
The chateau acquired its present appearance at the end of the 19th century. The southern wing of the chateau, the so-called Small Chateau, was rebuilt during the general reconstruction of the former pre-chateau brewery, and was first connected to the church by a passage conservatory, which was converted into a dwelling in 1928. Its northern front is adapted to the Romanesque façade, the southern one bears an open terrace overlooking the Podzámecký Pond, and it has a series of gables derived loosely from the motifs of Wallenstein Palace in Prague. The rest of the Small Castle is neo-Renaissance and richly decorated with sgraffiti. In the northern façade, the central part stands out with a volute gable (decorative, spiral-shaped) with a clock, topped with a turret.
The large chateau, rebuilt from the original fortress, now has a horseshoe plan, as the architect Stibral demolished part of the south wing and opened up the courtyard with a terrace over the pond, from which there is a beautiful view of the park. He rebuilt and enlarged the rest of it and placed a knight's hall with a coffered ceiling. The façade of the Great Chateau has not been substantially altered from its former state. The central façade, originally topped by a simple triangular gable, has been enriched by a complex superstructure with the figure of Assunta in the loggia, with turrets on the sides and a lantern on the top, but the articulation of the masonry has been left in its original state. The gate closing the gate to the courtyard is richly decorated.
On entering the Small Courtyard, the first thing that strikes us is the beautiful fresco of St George the Dragonslayer from 1892 by Hanus Schwaiger, which is on the wall next to the bay window and is the largest fresco work by this artist. To the left of it, you can see the statue of St. Hubert by the sculptor Celda Klouček. The second statue of him is on the inner staircase of the Grand Chateau. The opposite side with the windows of the Knights' Hall, which imitate the windows of the Old Chamber of Prague Castle, has a lunette cornice together with painted coats of arms of nobility with rusticated sgraffito and stepped shields. Under the arcaded galleries is a fountain with a wrought iron decorative grille, which is a copy of the fountain in the Small Market Square in Prague.
The west wing of the castle was connected by the architect Stibral with an extension to the old, newly modified spire, which is the real ornament of the western end of the spur. The tower with a wooden substructure, which he built on the north-west corner of the castle building, is new and probably stands on the site of the former castle tower, which was no longer there during the Empire reconstruction.
The castle cellars, carved into the rock, are partly reconstructed and partly decorated with smaller frescoes by Schwaigre. One of them depicts a Renaissance banquet, the opposite wall a humorous tournament duel, the ceiling Bacchus with signs and Bacchus and Noah receiving a grape from the Lord's hands, and the third a rococo drinking scene.
The interior of the chateau is new, last reconstructed in 2010; only two stoves from the older times have been preserved. One is baroque (in the Blue Room), made of sculpted and colourfully decorated tiles, the other from the end of the 18th century, made of flat, white and decorated with figural decoration (in the Mirror Room). During the last renovation, a conference centre was created on the first floor of the chateau, which is used not only for scientific seminars and meetings, but also for commercial purposes.
