The Trusteeship Council, one of the main organs of the UN, was established to supervise the administration of trust territories as they transitioned from colonies to sovereign nations. The Council suspended its activities in 1994, when Palau, the last of the original 11 trust territories, gained its independence.

The Chamber, originally designed by Danish architect Finn Juhl in 1952, has been revamped in a close collaboration between the UN and the Government of Denmark, with new furniture by Danish designers Kasper Salto and Thomas Sigsgaard.

Among the iconic aspects of the room is a statue of a girl with arms upraised, reading towards a bird which hovers with outspread wings above her head. Carved out of teak wood by Henri Starcke, a Danish sculptor, it symbolizes Mankind and Hope.
