Those are the human skeletons, bronze ware, polished stone, pottery and so on. After Sukhothai became the Thai capital, Si Satchanalai became the major town under Sukhothai. Especially it was located in the strategic location, such as on the river bank. In the middle there were mountains – Suwankhiri and Phanompleang Hills. So enemy could be seen far away. Due to its significant, key royal family members were sent from Sukhothai to rule Si Satchanalai. Even under Ayutthaya kingdom, Si Satchanalai was important to both Ayutthaya and Lanna (the northern kingdom, which is now the upper North of Thailand). So there were several battles between both kingdoms to occupied Si Satchanalai. In Si Satchanalai, therefore the combination of Sukhothai, Ayutthaya and Lanna arts and architecture are evidenced. Apart from that, it was the place to make pottery ware that unique for Sukhothai, called Sangkaloke. This area was once the major place to make pottery, both for use domestically and export to overseas, especially China.
