Petrovice Castle stands as a testament to architectural evolution and historical significance in the village of Petrovice near Rakovník, within the Central Bohemian Region of the Czech Republic. Originally constructed on the site of a sixteenth-century fortress that served minor nobility families such as the Renšpergárové and Hrobčičtí z Hrobčic, it was destroyed by fire at the onset of the Thirty Years' War. The castle's current neoclassical facade is the result of mid-nineteenth-century renovations led by Wallisové z Karighmainu, following its reconstruction into a baroque structure in 1709 by Jan Josef z Valdštejna.

The origins of Petrovice Castle are deeply rooted in the early modern period when Bohemia was part of the Habsburg Monarchy. This era was marked by significant religious and political upheavals, including the Thirty Years' War, which profoundly impacted the region's nobility and estates. The original fortress, built as a manorial seat for minor noble families, met its demise in a fire at the beginning of this tumultuous war. In 1709, Jan Josef z Valdštejna commissioned the reconstruction of the site into a baroque castle, incorporating significant additions such as a chapel and an oriel.

Architecturally, Petrovice Castle evolved from its sixteenth-century fortress origins to a baroque structure after being destroyed by fire. The mid-nineteenth-century renovations introduced a neoclassical appearance, characterized by a facade that includes a heraldic shield bearing the Wallis family crest. A notable feature of the castle is its chapel dedicated to Saint Michael, reflecting the religious influences of its time.

Ownership and administration of Petrovice Castle have seen dramatic changes over the centuries. The estate was initially founded in 1510 by Petr Holý z Chrástu with a manor. It passed through various hands, including Václav Dlask z Vchynic in 1542, Ferdinand Renšperger z Renšperka in 1587, and Jan Zeller z Rosenthalu in 1623 after confiscation. The castle's reconstruction by Jan Josef z Valdštejna in 1709 marked a significant turning point, followed by ownership under figures such as Jiří Olivier Wallis in 1732, Josef Siegereich in 1881, and Maxi Egon z Fürstenbergu in 1899.

Key events at Petrovice Castle include its destruction by fire during the Thirty Years' War and its subsequent reconstruction into a baroque castle. The mid-nineteenth-century renovations that gave it its current neoclassical appearance are also significant milestones in its history. These transformations reflect broader historical trends and the personal influences of its various owners.
