The square is the highest point of the downtown, the starting point of the birth of the town. During the Hungarian Conquest, Grand Prince Árpád established his royal centre here, as the island, which rising out from the marshland, could be protected well in case of a hostile attack. It was also well- known by Prince Géza, who built a four foiled, oriental type church, royal palace and a castle around it on the highest point of the island.

This church layout created from light ashlars can be seen in the square, in front of the Basilica. According to one viewpoint, it can owes its name to Prince Géza’s early castle, since its white castlewalls could be seen from far away. Another point of view, the white colour, which symbolizes the royal power, reflects in the town’s name, and the chair refers to the throne. Fehérvár had been mentioned first in the Establishing Charter of the Abbey of Tihany, in which Hungarian words appear in the Latin text as well: „feheruuaru rea meneh hodu utu rea”. This hardly resembles to the present Hungarian language, buti t means „Fehérvárra menő hadi útra”- onto the military road leading to Fehérvár.
