Academia Diplomática Andrés Bello (ADAB) of Chile is the institution responsible for training Chile's future diplomats and has also contributed to the preparation of diplomats from South America, Central America, the Caribbean, Europe, Asia, Africa, and Oceania.

[3][4][5] In 1963, the academy was established as a formal division of the Ministry of Foreign Affairs and in 1964, under the direction of professor and historian Jaime Eyzaguirre, a profound reform of the study programs was carried out, incorporating subjects such as Diplomatic Practice, Economics, International Organizations.

[6][7] On March 29, 1974, the Chilean Treasury acquired the September Palace by expropriation, a property located at Calle Catedral No.

The building houses the Ministry Library, Pinacoteca, Mapoteca, language laboratory, reception rooms, and an auditorium for ceremonies or events.

[8] In addition to teaching classes, seminars and conferences are held for students, international meetings, negotiations, official commitments, and activities typical of diplomatic functions.
