The Geological Museum was established in 1937 with the initiative and direct administration of the prominent geologist and honored scientist Prof. H. Karapetyan. The first exhibition of the Museum was organized on the basis of his rich collection, later it was supplemented by samples provided by mainly Armenian geologists. In 1944, after H. Karapetyan’s death (1943), the Museum took his name.

Out of the 11000 samples, the showcase samples fund is 2700, all of which are distributed in the following 6 sections:

• Paleontology Section
• Mineralogy Section
• Lithology Section
• Volcanology Section
• Ore Deposits Section
• Mineral Waters Section

In 2012, the special hall of minerals named after the American-Armenian collector A. Dildilyan was opened in the Museum, which exhibits 750 out of 1400 rare minerals samples from different countries donated by him. Minerals donated by Armenian geologists are also in the exhibition.

A number of innovations have been implemented in the Museum in recent years. The eco-club “Bnaget” was established, where children of different ages get acquainted with Armenian geology and ecological issues. The Museum organizes public classes, educational expeditions, and excursions within the frames of competitions proposed by the Ministry of Education and Sciences.

In 2016, the Museum joined the Dutch-Swiss izi.TRAVEL organization, which is aimed at discovering museums and cities and triggering the activities of various cultural and touristic organizations.

Starting from 2016, the Geological Museum is a member of the “Yerevan Card” City Pass Program. “Yerevan Card” is the official city pass which is a unique means for using privileges almost in all the institutions and services offered in the city. The card gives the right of free visit to the museums, attractions, free participation in the city tours and usage of city transport. In the framework of cooperation between Yerevan Card and Geological Museum, cardholders are given free access to the museum.

The Museum fund is over 11000 samples, 2700 of which are on display.
