The mosque is believed to be 300 years old. Constructed mainly in wood following the traditional Kerala style of architecture, the mosque is in possession of a handwritten copy of the Holy Prophet's sayings. The mosque, which was originally built by the Nair community, is considered to be an example of religious harmony. However, it is also believed that Bappan, the head of the Athilan family, which hailed from Nadapuram, bought the land measuring 5.50 acres from a Nair family and constructed the mosque. The mosque is said to have been inaugurated by Sainudeen Maqdoom II, the author of Islamic Karmasasthra.
If you walk around the mosque's premises, you can see the grave of Athilan Bappan, credited with supervising the construction of the mosque. The annual Uroos festival draws a large number of people. Korome mosque features along with Valliyoorkkavu temple and Pallikkunnu church in the pilgrim tourism circuit project of the Central Government in Wayanad.
