The Isdhoo Old Mosque is a historical site of great significance. It was here that historians discovered the Isdhoo Loamaafaanu, the oldest written records found in the Maldives. The Loamaafaanu is the oldest copper-plate book to have been discovered in the Maldives to date. The book was written in AD 1194 (590 AH) in the Evēla Dhivehi script, an old Dhivehi script that is no longer in use.
The Old mosque in the island of Isdhoo was built in 1701 CE during the reign of Sultan Ali VII and continues its use as a mosque till today. The mosque complex has the mosque building, old well and a cemetery with tombstones. With its fine carvings, entrance steps, carved wooden doors, lacquer calligraphy and decoration, the quality of workmanship is some of the finest in the country.
It is one of the finest surviving examples of a small coral stone mosque and has been maintained with minimal changes and in good condition. It is believed that the mosque was built from excessive materials left over after building the Malé Hukuru Miskiiy.
The mosque is located in a remote part of the island as it is usually the case with mosques built during those times.
