Istanbul is a major city in Turkey that straddles Europe and Asia across the Bosphorus Strait. Its Old City reflects cultural influences of the many empires that once ruled here. In the Sultanahmet district, the open-air, Roman-era Hippodrome was for centuries the site of chariot races, and Egyptian obelisks also remain. The iconic Byzantine Hagia Sophia features a soaring 6th-century dome and rare Christian mosaics.

Çanakkale is a city in northwestern Turkey in the Marmara region, on the Dardanelles Strait. It’s a gateway to the Gallipoli WWI battlefields, north of the narrow strait. On the grounds of the 15th-century Çimenlik Castle, Çanakkale Naval Museum Command contains historical artillery. The archaeological site at Troy, including an ancient theater, is southwest of the city.
