Negeri Sembilan starts just 50 km south of Kuala Lumpur. Negeri Sembilan, which literally means nine states, has many villages with patches of urban development. But that is slowly changing. Negeri Sembilan is well-known for its strong Minangkabau influences, which are still evident in its unique architecture and matrilineal society. The Minangkabau people migrated across the Straits of Melaka from Sumatra centuries ago and their traditional houses are distinguished by sweeping roof peaks shaped like buffalo horns. Some examples of these influences can be seen in the State Mosque and the State Secretariat Building. The Minangkabau people of Negeri Sembilan still practise the matrilineal social system known as the "adat perpatih", where the women are the head of the household, making the state the only one to adhere to such social norms. The capital of Negeri Sembilan is Seremban. The royal capital is Seri Menanti in the district of Kuala Pilah. Other important towns are Port Dickson and Nilai.
