Water
Sources at Halkalý
In
addition to the Forest of Belgrade, to the north of the city, the rich
aquiferous zone around Halkali west of the city provided the main local
sources of water (Çeçen
1991). The archaeology of water supply systems in both these areas
is dominated by remains of the Ottoman supply systems that superceeded
the Byzantine. Extensive repairs to the Halkali line immediately followed
the conquest of the city by Mehmet II and more lines were gradually added.
Some 17 individual channels dating to the Ottoman period are known to
have emerged from the Halkali region to supply the city. However the commanding
presence of the Mazulkemer, a massive two-tier water bridge perhaps alludes
to a longer period of activity. In form and composition the Mazulkemer
appears to be different from other Ottoman aqueducts on the same line.
For this reason it has been suggested that this aqueduct might originally
have been built for the Roman system, that was supplemented in the 4th
century by the long-distance line. Evidence of major rebuilding on this
bridge suggest that it was active for a considerable period of time at
at some point its arches required strengthening. The bridge is now within
the confines of a Military Zone, which has prevented closer study, but
at the same time served to protect the monument.
