Sarayburnu (Turkish: Sarayburnu, meaning Palace Point; known in English as the Seraglio Point) is a promontory separating the Golden Horn and the Sea of Marmara in Istanbul, Turkey. The area is where the renowned Topkapı Palace and Gülhane Park stand. Sarayburnu is included in the historic areas of Istanbul, added to the UNESCO World Heritage List in 1985.

The first settlement on the Sarayburnu, named Lygos (Greek: Λυγγος), was founded by Thracian tribes between the 13th and 11th centuries BC, along with the neighbouring Semistra, of which Plinius had mentioned in his historical accounts. Only a few walls and substructures belonging to Lygos have survived to date, near the location where the famous Topkapı Palace now stands. During the period of Byzantion, the Acropolis used to stand where the Topkapı Palace stands today.

In 667 BC ancient Greek settlers from Megara (near Athens) under the command of King Byzas established Byzantion at the Sarayburnu. Earlier, in 685 BC, the Megarans had established Chalcedon (present-day Kadıköy) on the Anatolian shore, across the Bosporus. Actually the oldest settlements in present-day Istanbul are found on the Anatolian side; such as the Fikirtepe mound which dates from the Chalcolithic period (Copper Age), with artifacts dating from 5500-3500 BC. In nearby Kadıköy (ancient Chalcedon), a large port settlement dating from the Phoenicians (which predates the Megaran settlement) has been discovered.

Ali Osman is a fictional character from the BBC soap opera EastEnders, played by Nejdet Salih. He was a member of the original EastEnders cast, appearing in the first episode on 19 February 1985. He remained with the show for nearly five years afterwards, making his final appearance on 10 October 1989. Ali was scripted as happy-go-lucky, which was in stark contrast to his highly strung wife, Sue (Sandy Ratcliff). Central to his storylines were his penchant for gambling, his tempestuous marriage, and the loss of his son to cot death, which was one of the first controversial storylines covered by the soap. He was created by Julia Smith and Tony Holland, the creators of EastEnders.

A Turkish Cypriot, Ali, his older brother Mehmet (Haluk Bilginer), and their family moved to London in 1975.
