Perili Köşk — The Haunted Mansion of the Bosphorus
The red turreted mansion on the Bosphorus shore whose popular name simply IS 'the Haunted Mansion' — built by an Ottoman pasha for a wife who left him, abandoned half-finished for eighty years while locals watched a woman's silhouette in its windows, and whose 1995 restoration workers reported she was still walking the corridors.

FILE 01 The Legend
Yusuf Ziya Pasha, an Ottoman statesman and diplomat, ordered the mansion at Baltalimanı in the 1910s; construction stopped in 1914 when the empire entered the First World War and its workers were conscripted, leaving a ten-storey shell — three visible floors over more below, crowned by the tower — that stood empty for eight decades. The name came from that emptiness: 'Perili Köşk', the haunted mansion, was what the neighbourhood called the abandoned castle on the shore. Two legends explain what haunts it. In the first, the Pasha built the house to match the beauty of his Egyptian wife, who — perhaps seeing the end of the Ottomans coming — left him for her home country; when two of his merchant ships sank and his finances collapsed, the house stayed unfinished, and Yusuf died in 1926 by the Nile, asking in his will that his tombstone be cut from the stones of the ill-fated mansion. In the second, darker telling, the Pasha imprisoned the young wife he built it for in the tower out of jealousy, and she left him too; her fate after the mansion is unknown. The second wife and three daughters remained in the house after his death and sold it in 1993; restoration began in 1995, and in 2007 Borusan Holding leased it to 2030 as Borusan Contemporary, an art centre open on weekends beneath the Fatih Sultan Mehmet Bridge.
FILE 02 The Sightings Log
The recurring witness list is unusually specific for a modern legend: during the empty decades, people living around Baltalimanı reported seeing the shadow or silhouette of a woman walking inside the mansion and appearing at its windows. When reconstruction started in 1995, construction workers claimed to see a woman's silhouette in the mirror of the young wife's room — the detail that carried the legend into its second century. Local tellings during the vacancy also insisted 'someone was living inside', and the building's floodlit silhouette under the bridge keeps generating passing reports. The mansion has been covered by The Guide Istanbul's haunted-mansion tour, Lonely Planet, and Turkish urban-legend coverage; it is now an office on weekdays and a public art gallery on weekends, which means the witnesses now include gallery visitors and Borusan staff.
FILE 03 The Skeptic’s File
The most honest explanation is in the name's own origin story: the mansion was 'haunted' because it was vacant — an eight-decade unfinished shell whose imposing silhouette under the bridge generated the stories, as Istanbul's own architectural writers put it, a psychological product of long vacancy rather than a haunting. The two wife legends contradict each other on every checkable point (which wife, why she left, whether she was imprisoned), which is the signature of folklore filling a vacuum rather than memory of an event; the tombstone-from-the-mansion detail exists only in the retellings. The 1995 mirror-sighting belongs to the classic restoration-worker ghost story pattern that attaches to nearly every long-abandoned building under scaffolding. No investigation, record or named witness has ever been published; the mansion's current occupants — an art foundation — do not claim a ghost, and the strongest evidence for the haunting remains the fact that everybody calls it that.
