Minyak Beku is a mukim in Batu Pahat District, Johor, Malaysia. Kampung Minyak Beku is where the famous chiseled rock is located, a big rock about ten feet in size (beside the police station). The big rock was chiselled by the Siamese (Ayudhya) to contain fresh water. It was said the Siamese soldiers came here by boat to attack Malacca but was defeated by Tun Perak back in the 15th century. The chiselled rock became famous where it later replaced the name of Bandar Penggaram to Batu Pahat. A brand new visitors center is being built there, and expected to open in 1Q10.
