ARTHILL, founded by a collector and an expert Hüseyin Kocabaş, the third-generation representative of the Kocabaş Family, which has enriched Turkish culture and Anatolian Civilization Heritage worldwide since 1918, is an international project with an academic and professional staff and solution partners. It is the only corporate firm in its field.

​

ARTHILL is not just a brand; it is a legacy. Undoubtedly, the foundations of collecting in Türkiye and today's private museums were laid with the Kocabaş Collection, recognized by authorities as the finest collection in the world in the 20th century, and the Kocabaş Museum, Türkiye's first private museum. ARTHILL, founded on the  experience, knowledge, and expertise of generations of collecting and museum professionals, strives to advance museums and collecting internationally with this vision and mission. It continues its research, projects, and publications on the subjects of culture and art. It provides a wide range of professional services to museums, institutions, organizations, collectors, and art lovers, from museum establishment to collection development, including appraisal, consulting, artwork tracking, and acquisition.

Transforming its century-long history into a corporate structure, ARTHILL today operates with a multifaceted structure in the worlds of art, luxury, and investment. The companies and sub-departments under the ARTHILL GROUP umbrella offer services in "Auction and Exhibition Organizations," "Appraisal and Valuation," "Heritage Management and Investment," "Digital Arts," and "Entertainment." It also sells antiques and works of art, precious stones and jewelry, and priceless and elusive pieces through private and online platforms.
 

ARTHILL is an institution that represents cultural authority and trust with its strong academic and expert staff comprised of the most valuable (top) experts and specialists in their respective fields. The appraisal reports, certificates, provenance documents, and academic dossiers prepared for works ensure collectors, art lovers, and investors can purchase with confidence. ARTHILL transforms every purchase not only into an investment but also into a scientifically and historically secured legacy. Every piece that passes through ARTHILL's curation is an icon, invaluable in its historical and noble spirit.

ARTHILL is the only institution with its priceless "Ottoman Dynasty" and "Legacy" collections,  that carries the legacy of the past into the present and entrusts it to the future. This collection is not merely a collection of works of art; it is the memory of a dynasty, the voice of a civilization, and the memory of a culture. Thanks to this unique collection, ARTHILL holds unparalleled prestige in the global cultural arena, not only as an art brand but also as the bearer of the Ottoman Dynasty's legacy.

​

One of the strongest symbols of ARTHILL's corporate vision is Serra Hanım Sultan, a member of the Ottoman Dynasty and granddaughter of Sultan Murad V. Serra Hanım Sultan has the title as the "Imperial Legacy & Nobility Director" at Arthill Group. This  demonstrates that ARTHILL is not merely an art brand, but a symbol of trust and cultural authority, crowned with centuries-old dynastic nobility.
