The Kapagiannidis Residence is the former dwelling of wealthy Greek banker Konstantinos Kapagiannidis (Gr: Κωνσταντίνος Καπαγιαννίδης). Today Today it's called the Atatürk Pavilion. The mansion is located on the slopes of Soğuksu only 4 km south-east of Trabzon in Turkey. Kapagiannidis used the residence as his summer retreat. He built it in 1890 (some sources say 1913).
The mansion was built to Western standards and comprises stone walls. The interior includes tiled flooring and a heating system which was well ahead of it's time. The residence was renamed Ataturk Pavilion/Kiosk after the exchange of populations between Greece and Turkey in 1923. The title Ataturk refers to Mustafa Kemal who is regarded as the founder of modern day Turkey. Ataturk visited Trabzon three times and on his second visit in 1930, stayed at the residence. The then government of Turkey decided to gift him the house. It's currently used as a museum.
