The Zsámbék Castle was built on the spot of a 14th-15th century castle by the Zichy family in the 1690's as a castle, and it was turned into a palace in the 18th century. The early Baroque palace has a plain exterior look with two corner towers.
From 1904, the Sisters Hospitallers of the Sacred Cross used and renovated the building. Probably during these renovations were the medieval great hall and the outbuildings removed. Later the palace was used by a kindergarten and different schools. Since 1929, the palace houses the Vilmos Apor Catholic School.

From 1900 to 1908 it was rebuilt at the behest of the German kaiser Wilhelm II. Today it is a major tourist site, attracting more than 500,000 visitors a year.
The first records of a castle built by the Hohenstaufens date back to 1147. The fortress changed its name to Koenigsburg (royal castle) around 1157. The castle was handed over to the Tiersteins by the Habsburgs following its destruction in 1462. They rebuilt and enlarged it, installing a defensive system designed to withstand artillery fire.
The fortification work accomplished over the 15th century did not suffice to keep the Swedish artillery at bay during the Thirty Years War, and the defences were overrun.
