Standing for centuries confounding scholars: the Maiden Tower (UNESCO with the old city) — cylindrical, original purpose disputed (temple? observatory? fort?) and wrapped in the name's legends — its climb opening the full view of Icherisheher and the bay. The floor exhibits tell the tower's theories with the roof as the goal; sunset gilds the old city below; fold into the single Icherisheher loop with the Shirvanshahs' palace.
