Overview of the Golsang Museum

The Golsang Museum, situated in Tehran, Iran, is a specialized museum focused on the preservation and study of lichens. Established in 2012 under the supervision of the Organization for Scientific and Industrial Research, the museum currently houses about 600 lichen species, all playing a critical role in preventing dust and particle pollution. Lichens are also extensively used in medicinal applications and are key indicators of sustainable ecosystems.

Understanding Lichens

Lichens are unique organisms that are formed by a symbiotic relationship between a fungus and one or more photosynthetic partners, usually either a green alga or cyanobacterium. This association results in a composite organism that has a form and function distinct from its individual components.

Lichens, often seen as velvety patches on rocks and tree trunks, especially in the forests of Northern Iran, are fascinating organisms formed by the symbiotic relationship between fungi and one or two types of algae. They thrive in clean air environments, be it desert, polar, or forest habitats. There’s even a type of lichen that grows in water!

Lichens can endure extremely cold temperatures, as low as -60 degrees Celsius. Some grow only to a size of 1 millimeter, while others can live up to 4000 years! These hardy organisms play a significant role in cosmetics, healthcare, and pharmaceutical industries. In countries like Italy, lichens are used as reliable and non-manipulable indicators of air pollution.

Unfortunately, according to Dr. Sohrabi, the founder of the Golsang Museum, the potential of lichens is yet to be fully explored in Iran due to various challenges. However, the museum has a strong audience base among graduate and doctoral students who hope to further study and utilize these valuable organisms in various practical applications within the country.

The Golsang Museum is a place for everyone; there are no age restrictions for its visitors. It even warmly welcomes pre-school children, teaching them about the value of lichens in a language they can understand.
