This ancient Syrian capital was once the third-largest city in the Roman empire, after Rome and Constantinople. Drive to the top of the mountain to see the ruins of the Byzantine fortress (though the view is more impressive than the ruins), and visit some of the city mosques. A special treat for Biblical scholars and history buffs is the red-rock St. Peter's Church, where Peter converted some of the earliest Christians. Also be sure to see the Baths of the Sinners (excellent reliefs) and the Hatay Archaeological Museum (don't miss the mosaic of Oceanus), and the nearby Crusader castle, built atop the foundations of a Hellenistic fortress in the nearby town of Bagras. Worth seeing as well is Yakacik, a restored 16th-century urban complex featuring a castle, courtyards, caravanserai (where caravans rested), mosque and covered market. Three nights are needed to see Antakya and vicinity. 325 mi/525 km southeast of Ankara.
