Kampung Laut Mosque is considered to be the oldest mosque in Malaysia, built in 1676. The mosque was originally located at Kampung Laut, in Tumpat district of Kelantan about two miles (3.2 km) downstream from the town of Kola Bahru. During its construction, the mosque is believed to sit at least three-quarters of a mile (1.6 km) from the riverside of the Kelantan River and near the seashore.

This mosque’s design is influenced by the Nusantara style. The floor plan is square in shape. The roof of the mosque is a three-tiered Meru roof (pyramidal roof). The end of ridge cap is known as ekor itik in Kelantanese dialect, and it symbolises a dragon. The way the dragon is symbolized in this mosque is that it was formed into something called som that are located at the four corners of the mosque’s roof. Som is divided into three parts that are known as the head, body and tail. The shape of buah buton at the tip of the roof is the result of refinements made in the shape of a Buddhist stupa. The uniqueness of this mosque is the existence of balai lintang (foyer hall) and waka! orang kaya (dignitary’s gazebo) which were built in the 1950s by Orang Kaya Hussein. This Balai lintang is located in front of the main prayer hall opposite lo the mosque’s main entrance. Balai lintang was built in 1908 at the time of Sultan Muhammad IV. The minaret, wakaf orang kaya and ablution pond are located on the right side of the main entrance of the mosque. The old minaret that had collapsed was originally located at the front of the mosque.
