The Golden Horn passes through the city to join the Bosphorus, which allows the waters of the Black Sea to reach the Sea of Marmara (and eventually, the Aegean Sea into the Mediterranean). The Bosphorus is lined by beautiful buildings including Kız Kulesi and Topkapi Palace, but perhaps the best-known attraction in the city is the Ayasofya Camii, or Hagia Sophia.
