There are two things to do at Troy: walk the archaeological site, and visit the Troy Museum a kilometre away. Both are essential. The site itself is the layered remains of nine successive cities stacked on the same hill over three and a half thousand years — small in area but rewarding to anyone willing to read the signage and use the imagination. The museum, opened in 2018, displays the finds and explains the layering more clearly than the site itself can.
A signed walking path loops the mound in about 90 minutes, passing the famous Schliemann's Trench, the East Gate, the late-Bronze-Age walls of Troy VI, the Megaron at the centre, and the Roman-era Odeon and Bouleuterion on top. Allow two to three hours for the site, two more for the museum. Most visitors arrive on a half-day tour from Çanakkale, often combined with the Gallipoli battlefields across the Dardanelles.
