Visitors wishing to discover the mysteries of Lembah Bujang should make a stop at the Lembah Bujang Archaeology Museum located at Bukit Batu Pahat, Mukim Merbok, Sungai Petani, Kedah. This museum is a treasure house of recovered artifacts from historical sites dating from the early 5th to 14th century AD. There are some 1,000 artifacts exhibited in the museum and another 2,500 still being studied.

Lembah Bujang Archaeology Museum has two main galleries that showcase:

• Southeast Asia's central trading port handling cargo from Arab, Chinese and Indian traders as well as maritime traders from the Malay Archipelago.

• Architecture and cultural artifacts connected to religion and proving the existence of a Hindu/Buddhist civilisation using Lembah Bujang as an entrepot from the 3rd to the 12th century AD.

The Bukit Batu Pahat Shrine is situated on the west of Sungai Batu Pahat. about 3 km north of Kampung Sungai Merbok. Among the remains of this temple are the Siva Candi and 66 sites of wooden poles. It is believed that this monument was made of wood besides granite stones. However, all the wooden poles and roof of the Shrine have deteriorated over the years and do not exist anymore.

 Many centuries ago, a highly civilised ancient Mala kingdom existed in Lembah Bujang. During the 5 century AD, traders from countries such as China, India and the Middle East knew of its existence and fame as an entrepot. This was due to its strategic position along the trade route between the Mediterranean Sea to the West and China to the East.

Tamil poets, Arab merchants of the 4th century and I-Tsing, a monk who sailed from China to India, knew of the existence of this civilisation in Lembah Bujang. The Hikayat Merong Mahawangsa (Tales of Merong Mahawangsa) calls it 'Langkasuka'.

However, the spread of Islam resulted in the decline of Hindu- Buddhist influence and the port consequently became less important. The emergence of new ports such as Malacca and other cities throughout Southeast Asia also contributed to the deterioration of the port at Lembah Bujang. Today, it continued to develop under the new identity of an Islamic Malay kingdom, now known as Kedah Darul Aman.

Archaeological research in Lembah Bujang was initiated in 1840 by colonial researchers and was only taken over completely by local researchers during the 1970’s. In 1864, Colonel James Low started carrying out research in Lembah Bujang. At the start of the 20th century, two quantity surveyors found the remains of a temple at the peak of Gunung Jerai. From 1920 to 1930 I.H.N Evans carried out research in Lembah Bujang.

H.G. Quaritch Wales and his wife Dorothy red discover 30 Candi sites, 29 situated in Lembah Bujang and one in Seberang Prai during the period 1938 - 1939. Alastair Lamb excavated and reconstructed Bukit Batu Pahat Candi (Site 8) in the late 1950’s. In 1961 Paul Wheatley also carried out research on the historical development of Lembah Bujang.

The early 1970’s marked a new era of archaeological research in Lembah Bujang, carried out by local archaeologists. The Department of Museum and Antiquity Kuala Lumpur produced many local researchers who have carried out continuous research in Lembah Bujang. Archaeologists from local higher institutions of learning have also been involved in this research.

The surrounding area of Lembah Bujang Archaeology Museum is an ideal place for families as there are many recreational activities available. For instance, the tropical rainforest landscape is full of flora and fauna unique to the region, and is perfect for hiking or picnics. The scenic Sungai Merbok is also suitable for swimming, hiking or picnics. For those interested in agro-tourism, there are paddy fields to visit in the vicinity.

Visitors can also enjoy the scenic cascading waterfall located nearby or the view from Gunung Jerai, a 1,380-meter high mountain rising majestically out of the flat landscape in the region. This mountain was considered a sacred mountain during the time of the Hindu-Buddhist influence in Lembah Bujang.
