Ketchchimalai Mosque, also known as Ketchimalai Dharga, is located on a headland overlooking the port of Beruwala, on the southwest coast of Sri Lanka.

According to local folklore, the mosque is built at the spot where the first Muslim Arab traders landed and subsequently settled in the area.

Allegedly one day, when the chief of the Masjid Al-Abrar in Beruwala was cleaning the tomb he stepped on a sharp thorn following which he rest under a tree and fell asleep.

It is essentially a squarish white building, with an ornate arched exterior, curving dutch-style gables, with an unusual domed minaret crowned with a crescent-and-star ornament.

The mosque is the focus for a major Eid al-Fitr festival held at the end of Ramadan, with large numbers of pilgrims attending.
