Van - Sardur Burcu (Madir Burcu)

On the northeastern side of Van, under the citadel rock, the remains of the impressive harbor walls acquired the name "Sardur's Castle" in ignorance of their true function. At Tushpa, as at several other places around Lake Van, Sardur had a solid mole built of black basalt blocks which were quarried from Alniunu near Gümüsdere 17km/10mi to the south.
