Archaeological excavations show that it had a citadel. The stone walls were almost 5 metres thick and probably 8 metres high, with walls of dried brick on top. The streets of Troy were paved and guttered. The city covered an area of about 350,000 square metres and was the largest city on the Aegean Sea.
The city was a centre for the development of handicrafts, especially pottery and textiles. The city was surrounded by arable land, vineyards and olive groves. Archaeologists have found numerous horse bones, which indicate that the inhabitants were involved in horse breeding.
