Overview
Mission
The organization's mission is to preserve, protect, and manage greek antiquities - art, artifacts, and antiquities dating from prehistoric times through the dark ages - consistent with the patrimony laws of the hellenic republic. Through gifts, bequests, and loans, the organization is committed to ensuring these cultural treasures are maintained for the public benefit, with the eventual transfer of possession to the nicholas and dolly goulandris foundation -museum of cycladic art, where they can be further studied, exhibited, and appreciated.
What it reported doing in 2025
In 2022, the organization received the leonard a. Stern collection of cycladic art, a group of 161 works made in the cycladic islands of greece, primarily in the early bronze age (3200 to 2000 bce), the metropolitan museum of art in New York (the met) continued throughout the tax year to house the leonard a. Stern collection of cycladic art, except during a period commencing in the final quarter of 2023 when a selection of works from the collection was transported to athens, greece, exhibited publicly by the nicholas and dolly goulandris foundation-museum of cycladic art (the mca), and featured in a catalogue published by the mca. The organization in tandem with the mca also continued planning and preparation for exhibition of the entire collection at the met, commencing in january 2024. These activities were undertaken for study, conservation and safekeeping of the collection, in furtherance of the organization's mission to preserve, promote and protect greek antiquities. It is the policy of the organization that these works be used directly in furtherance of that mission and that they never be disposed of by sale or exchange.
