The Buda castle was built in the late Gothic style during the 14th century at the southern end of the hill where it currently stands. 

In the middle of the 13th century, after the Tatar invasion of 1241, King Bela IV of Hungary began rebuilding all the fortresses, reinforcing them with stone walls, and ordering the erection of about a hundred new castles. Thus, in 1244, he ordered the construction of a fortress in Óbuda, which soon began to be populated in a position close to the current one. From this, the following Hungarian kings would spend a lot of time in this new fortress without losing direct contact with Székesfehérvár. The strategic, commercial, and political importance of Buda continued to grow, and in 1310, it became the official residence of the Hungarian monarch and his court.

The castle has undergone massive restoration in the 18th century and extended in the 19th century. The castle as we know it was finished in 1904 and is one of the most impressive residences for royalty in Europe.
