Agop Batu Tulug Caves, Archaeological caves in Kinabatangan district, Malaysia

Agop Batu Tulug Caves is a group of caves in a 39-metre limestone rock of the Labang formation near Kg. Batu Puteh, about 80 km south of Sandakan. The site has four main caves: Agop Sawat (upper), Agop Lintanga (middle), Agop Suriba (lower) and Agop Dimunduk. Agop Sawat and Agop Lintanga hold about 125 carved wooden coffins made of belian hardwood.

Research teams discovered this burial site in 1984, which led to systematic archaeological investigations of the site. The wooden coffins date back to a period roughly 500 to 900 years ago.

The coffins are carved with buffalo heads, crocodiles, house lizards and snakes. A crocodile stands for death and the power of darkness, while the bugang bird, dog, rooster and deer were friends of the heroes in Kinabatangan legends. Some coffins are shaped like animals linked to Orang Sungai beliefs.

The caves sit in an isolated limestone rock by Kg. Batu Puteh, in a bend of the Sungai Kinabatangan about 80 km south of Sandakan and 41 road kilometres from Kota Kinabatangan. Since 6 July 1996 the Sabah Museum has maintained facilities here, including toilets, staircases, an office building and overnight cabins. The climb to the upper chambers involves stairs; wear sturdy shoes for uneven ground.

The name mixes three languages: agop is "cave" in the Sungai language, batu is Malay for "rock", and tulug is Cebuano for "to go to sleep", a reference to the caves as a resting place of the dead. The site lies in a river bend of the Sungai Kinabatangan, about 80 km south of Sandakan.
