The Pelince Memorial Museum was developed by the project of architect Georgi Konstantinov (Ѓорѓи Константинов) and the monumental mosaic facade is the work of the Macedonian contemporary artists Rubens Korubin (Рубенс Корубин) and Ilija Penushliski (Илија Пенушлиски).
The museum exhibit is made in an ambiental and authentic manner, as at the time when the First Meeting of ASNOM was held on August 2, 1944 in the Monastery Prohor Pcinjski (Прохор Пчињски) which today is located in Serbia.
On the first ASNOM session were present 116 delegates from Vardar, Aegean, and Pirin part of Macedonia. In addition, also were present the representatives of the English and American military mission in Macedonia during World War II.
The session was opened by the oldest member of Parliament, Panko Brashnarov (Панко Брашнаров), and then were adopted important decisions, which laid the foundation of the Macedonian state.
One of the most important documents of the session include Decisions which constitute Macedonia as an equal federal unit of Democratic Federal Yugoslavia, implementation of the Macedonian language as an official language of the Macedonian state, etc.
The first meeting of ASNOM marks the beginning of the current existence of Macedonia as a free state in federation with the Yugoslav people, and since 1991 as an independent state.
