Seremban is the capital of the Malaysian state of Negeri Sembilan. The city was founded in the 1870s, following the discovery of tin ore deposits in the area. The city experienced an influx of Chinese and Malay immigrants and quickly developed into a prospering mining and commercial centre. Nowadays Seremban is a medium-sized town. Istana Ampang Tinggi is a 19th century palace in Seremban with the structural layout of Minangkabau houses - the horn-shaped roofs.
