Koto Gadang is a small village which produced great men such as Agus Salim, Sutan Syahrir and Rohana Kudus. That village is located at approximately height about 923 meters above sea level and flanked by Mount Singgalang and Mount Merapi. The name of Koto Gadang its means big city, same as well as Kota Gede in Yogyakarta (middle java). There are also silver crafts and embroideries.

The unique characteristic in this village is the residential house model which look likes the villa house of the Dutch people (old house) and those are different from the traditional Minangkabau house model. This is because this village is used to be a resort for Dutch people who worked in Padang City. It was said that Dutch people were happy to stay in Kota Gadang because local people there are more open and receptive to people outside the region. So many educated people from Minangkabau province were born of Koto Gadang village.

Cluster-type residential houses are divided into 4 clusters; there are Caniago, Koto, Piliang, and Sikumbang. The roof cover of the houses made of zinc, instead of tile that made from terracotta, it had to do with the local community trust that is not good for a house covered roof by the something from the ground because the ground/ soil is symbolizing a place for people who have died.

The village’s atmosphere is very quiet as there was no pulse of life. This is because the people who like to go abroad to leave home so that was left was some house wife and children.
