The sarcophagus that draws the crowds here was never Alexander's — it is named for the reliefs of him fighting Persians carved across its marble sides. The Istanbul Archaeology Museums began with that discovery: Osman Hamdi Bey, an Ottoman painter turned archaeologist, unearthed it in a royal necropolis at Sidon and, in 1891, opened a purpose-built home for it beside Topkapı's outer garden. He also wrote the law that stopped antiquities leaving Ottoman soil, which is why so much stayed. Architect Alexandre Vallaury shaped the neoclassical facade to echo the very sarcophagi inside, and three buildings now share the grounds, including a tiled pavilion from 1472.
Inside the main hall the Alexander Sarcophagus still carries faint traces of its original paint, its battle and hunt scenes cut in deep, crowded relief. Rooms of classical statuary lead on to the Ancient Orient wing, where blue-glazed lions from Babylon's processional way stand near a clay tablet recording one of the earliest peace treaties ever struck. Outside, columns, capitals and weathered sarcophagi rest under the trees beside Gülhane Park.
