These are the ruins of the 13th C. Premonstratensian monastery in Zsámbék (Hungary). It is one of the better preserved medieval monuments surviving within the borders of modern Hungary. Its architecture is an interesting blend of late Romanesque and early Gothic elements (most visible in the mixing of rounded and pointed arches) and shows some links to France which can be explained by the fact that the abbey was founded by a noble family of Aynard who came to Hungary from France in the time when a French princess was a queen of Hungary. Most of the monks who lived here, at least initially, would therefore come from France, invited to this frontier realms by their French protectors. The church was heavily damaged by the Mongols around 1241 so most of what can be seen today, probably dates from around 1250s when the site was rebuilt.
What makes Zsámbék particularly important is that it is one of the sole survivors which escaped complete destruction during the over hundred and fifty years of the Turkish rule in Hungary. Of all the three major medieval kingdoms of central Europe; Bohemia, Poland and Hungary, the cultural heritage of the last one is the least preserved. Hungary was a powerful kingdom which had close connections with the courts of western Europe, the Byzantine empire and the crusader states in the East yet, because of the Turkish occupation, most of its medieval monuments have been destroyed; old towns, monasteries, churches, universities... Of all the cathedrals of medieval Hungary only one, the medieval cathedral of Transylvania in modern Romania is preserved, all the others are lost. Zsámbék was interesting, to me at least, as a glimpse of medieval Hungary, offering a chance to imagine how the kingdom might have looked like, have it not been ruined in the 16th C.
