Adina Mosque, National monument mosque in Gazole, India.

Adina Mosque is a large rectangular structure in Gazole, India, distinguished by its many domes and detailed stone ornamentation throughout its arches. The interior features a central ribbed barrel vault and an open courtyard that sits at its heart.

Sikandar Shah, second sultan of the Ilyas Shahi dynasty, commissioned the Adina Mosque in 1373 and it was completed in 1375, after the Bengal Sultanate defeated the Delhi Sultanate in 1353 and 1359. Built as an imperial mosque, it was the largest in the Indian subcontinent at the time. Sikandar Shah was later buried in a tomb chamber attached to the western wall.

The name Adina is understood to mean Friday, linking the building to the weekly congregational prayer. Its terracotta panels were the first on a mosque in Bengal, mixing Islamic motifs with Pala-Sena designs such as lotus petals, chain-and-pendant patterns and a tree linked to the Buddhist Kalpataru. Carvings of elephants and dancing figures survive on some exterior walls.

The mosque lies beside National Highway 12, about 20 km from old Malda town, with the Adina Deer Park opposite. The prayer hall's dark wooden plank floor and the courtyard's uneven ground call for careful footing. The 19th-century earthquake damage left parts of the structure in disuse, so some areas are best viewed from a distance.

The prayer hall's pointed arches rest on thick columns with scalloped, petal-edged square capitals and shafts of dark polished stone cut with vertical flutes; twelve stand in rows over wide dark wooden planks. The minbar north of the central mihrab keeps a kirtimukha motif, a Hindu device recut for mosque use.
