URALMI JELKÉPEK - BUZÁS GERGELY: Szabályos alaprajzú vár paloták mint az uralkodó hatalom jelképei a XIV-XV. században
This model of building originates in Gothic art of the Holy Land, its special function of a castle, however, was established in France and Italy in the 14 th century. From the end of that century it was widespread in most parts of Europe. This general architectural fashion explains the appearance of the individual Hungarian subtype. The castle of Diósgyőr, our first and most exquisite record from the end of the 14 th century, with its four corner towers, bears witness of the direct influence of Southern French (Avignon, Sourge) architecture of the 14 th century. This area, however, cannot be regarded as the only source of Hungarian construction of the time: Tata resembles the Lombard castles in style, more specifically Mantova and Ferrara, while Ozora is similar to the castle of Verres, built in the 1390s in the Aosta Valley. The prevalence of this castle type in Hungary in the Anjou and Sigismundian age indicates the cultural closing up of the country's royal court and aristocracy to the international gothic culture of European courts, around 1400. At the end of the 14 th century, following the Hungarian example to a great extent, Moldavian princes had built castles, like Scheia, Suceava and Neamt, similar in style and structure.
