It is a "brick-built mosque, with a square prayer chamber and a verandah on the front".
It was built by Rafa’t Khan, in 1495, during the reign of Alauddin Hussain Shah.
[4] Amitabha Gupta writes in his photogapher's note: This brick-built Mosque at Kheraul alias Kherur with a single domed square prayer chamber and a triple domed verandah on the front with four minarets at four corners was erected by Rafa't Khan in 1495 AD during the reign of Alaud-Din Husain Shah on the basis of two inscriptions on the mosque.
The hemispherical dome of the main prayer chamber fell down in the earthquake of 1897.
Only a handful of mosques have such decorations on their walls and they predate the famous terracotta temples of Bengal which were constructed between 17th to 19th century.
