Rumah Gadang Datuk Sinaro Garang, Traditional Minangkabau house in Gunung Toar, Indonesia.

Rumah Gadang Datuk Sinaro Garang is a traditional Minangkabau wooden house with a distinctive curved roof and upturned roof peaks resembling buffalo horns. The structure contains sleeping quarters, communal gathering spaces, and areas for ceremonies, with carved wooden walls serving as both decoration and natural ventilation systems.

Built around the 1920s, this house is one of seven rumah gadang of the Piliang clan in Toar village, Gunung Toar, Kuantan Singingi. It serves as the gathering place for the descendants of Datuak Sinaro Garang and is listed as a cultural property of Riau Province. Its 20 wooden posts are said to represent the 20 customary laws of Kampung Toar.

The building's name honors a significant community leader, and its layout reflects the principle of property passing through female family members, a practice central to Minangkabau social life. This custom has shaped how the house functions within the extended family structure.

The house is located in a rural village area and is accessible on foot through the local pathways. It is best visited when family members are present, as this allows access to the interior spaces and a genuine sense of how the building is used.

The carved panels carry floral and vine motifs in a named Minangkabau pattern, Aka Cino Tangah Duo Gagang, not geometric designs. The main room is also divided by a partition separating men's and women's spaces, and the 20 wooden posts stand for the 20 customary laws of Kampung Toar.
