Giber Mihály: Adatok az egri püspökvár középkori építéstörténetéhez
Mihály Giber Observations on the Architectural History of the Medieval Episcopal Castle This study focuses on the architectural history of the cathedral church that once stood in the precincts of the medieval castle, as well as the buildings that once stood along the northern wall of the castle. In analysing the medieval history of the cathedral we suggest that following the recent findings of Krisztina Havasi and Gergely Búzás in particular, it is now time to reconsider some aspects of the architectural histories written by Mihály Détshy and Károly Kozák during the 1960s and 1970s. At the present time it is possible to trace the evolution of the church's ground plan from the 12 t h century onwards with some degree of certainty. From the 12 th century one can talk in terms of a triple-aisled basilica, each aisle of which culminated in a semi-circular apse, which was remodelled firstly in about 1200, and then again in the mid to late 13 t h century, by which time the rebuilding work was being done in the Gothic style. The 12 t h century apses managed to survive the reconstruction work. Two towers with rectangular ground plans were added to the west end in the second half of the 14 t h century. From the second half of the 14 t h century a substantial triple-aisled chancel was added containing an ambulatory and ambulatory chapels. The addition was somewhat wider than the earlier cathedral church, while being about half its length. The 3/8 polygonal ambulatory chapels completely surrounded the new chancel. At the turn of the 16 t h century the chancel addition was demolished, and in its place a new choir was built with an ambulatory whose vaults rose to the height of the main aisle in what was a hall church elevation, whose measurements both in terms of its length and height were similar to those of the older part of the cathedral built in the 12 t h—14 t h centuries. 80
