KATALIN H. GYURKY THE MEDIEVAL TOWN WALLS OF BUDA, I. The author conducted excavations near the building of the National Archives (No. 1. Petermann biró Street) in 1972. Near that street the remains of a medieval dwelling-house were found and, on the northern side of the site, the double wall of the medieval town which provided protection to the north. Between the dwelling-house and the inner town wall there was a wide strip of land without buildings. The dwelling-house could have been built on the edge of the geological surface of the hill in the 14th century at the earliest. Similarly on the edge of the original slope the inner town wall was erected in the 13th century. The structure of the wall was strengthened by built-in beams. Documents dating from the nineties of the 15th century bear evidence of the existence of the outer (second) town wall. Relying upon the results of the excavations conducted at the Dominican monastery the date of the construction ofthat wall can be determined as the time between 1390 and 1430. Apart from these two medieval walls there is also a third one, at present it is bordering the Castle Hill. It is known of that wall that it already existed at the time of the siege in the year 1686, consequently it had been built during the Turkish rule, presumably on account of the bad condition of the medieval town walls.
