Asasi Mosque, 18th-century mosque in Sigando, Indonesia

The Asasi Mosque stands on a 25 by 22 metre plot in Sigando, Padang Panjang. Its main prayer room, 13.1 metres square, is raised about a metre on a wooden understructure and is held up by eight pillars plus a central tonggak macu post 1.5 metres in diameter and 15 metres tall. Walls carry Minangkabau floral carvings, and the three-tiered zinc roof is concave to shed rain quickly.

This site was originally founded in 1770 as Surau Gadang and has survived multiple strong earthquakes, including ones in 1926 and 2009. The way wood and construction were used helped the structure endure these tremors.

The mosque serves the community as a place for religious gatherings and Quranic study, where visitors can sense the commitment to transmitting knowledge. People use the space daily for prayer and learning, making it a living center of community life.

The ablution area lies outside the iron fence, beneath the house of the mosque's garin, and is reached by a descending staircase on the west side. Its water comes from a spring near the mosque that locals call "bulaan". The main prayer hall sits about one metre above ground level, so visitors climb cement steps at the left and right of the enclosed veranda.

The woodwork comes from craftspeople in Nagari Pandai Sikek, a village known for its exceptional carpentry and carving skills. These local artisans have passed down their traditional abilities through generations and shape the building's appearance through their skilled work.
