One of the interesting mansions in Sariyer, a three-storied building, was chosen as the locale of a beautiful museum founded by the Koc family. Rare objects collected over the years, costumes and artifacts reflecting the lifestyles of past centuries, valuable fabrics, and gold, silver and porcelain wares are displayed in the museum. After the Koc family acquired the archeological collection of Huseyin Kocabas, the building next door was bought and added to the museum to provide space for the exhibition of this rich collection. This modern and impressive exhibition is in chronological order and it contains pieces from the Neolithic age and Hatti, Hittite, Urartu, Greek, Roman, Byzantine and Seljuk periods.
