What is the Troad region surrounding ancient Troy?

The Troad (or Troas) is an ancient district defined by the northwestern projection of Asia Minor into the Aegean Sea. It encompasses the territory surrounding the ancient city of Troy.123

Geographically, the region is bounded by the Dardanelles and the Sea of Marmara to the north, the Aegean Sea to the west, the Gulf of Edremit to the south, and the Ida mountain range to the east. The landscape features rugged, wooded terrain in the south and east, while the Scamander River flows from the Ida mountains through the hills to a plain in the northwest.21

Beyond Troy, the Troad was home to several other notable settlements, including the coastal cities of Sigeum, Alexandria Troas, and Assus, as well as interior sites such as Neandria and Scepsis.2
