Excavation of the Beinan site in the past ten years
5-1. The site’s landscape in 1993:
Prior to the establishmentthe National Museum of Prehistory, trial excavation had been conducted within the park area to see whether the addition of new park facilities will affect the archaeological site. However, since more than 80 percentof the land of the Beinan site is private property, some farmers dug up their land in 1993 and unearthed several slate coffins and other relics. The Ministry ofthe Interior commissioned the museum to deal with the problem.
In 1996, the museum gained permission from the Taitung County Government for temporary usage of a stretch of land expropriated for road construction. The land was next to the Beinan Cultural Park, and the museum set up scaffolds to carry out an archaeological excavation and welcomedvisitors to understand the process of archaeological work and witness the unearthed structures and relics.
5-2. New findings at the Beinan site:
Carbon-14 dating determined that three cultural layers existed at the Beinan site about 2,000 to 5,000 years ago. Prehistoric residents had lived on the site for a long time from the Neolithic Ageto the Iron Age.
The relicsunearthed at theBeinan site belonged to the Jomon pottery culture from 5,000 to 3,500 years ago and the Beinan culture from 3,500 to 2,000 years ago.Both cultures are classified as Neolithic.
Recently, researchers at the National Museum of Prehistory have confirmed that in the final prehistoric stage at the Beinansite, stoneware was infrequently used, the style of pottery had changed, and burial customs had changed from using slate coffins to going without coffins. Meanwhile, the fact that ironware was unearthed here indicates that the prehistoric culture entered the Iron Age about 1,700 years ago. This particular archeological layer is likely related to the ancestors of Taiwan aborigines.
5-3. Slate coffins unearthed at the Beinan site:
There are several largeclusters of slate coffins at the Beinan site and more than 1,600 slate coffins have been excavated. The coffins, which were made of slate slabs, were generally buried in the northeast-southwest directionfacing Dulan Mountain. Adults, children, and even newborn babies were all buried in slate coffins.
Slate coffins reflected the burial customs and values at that time. Although not every slate coffin contained mortuary objects, a large quantity of such objects were found inside most of the unearthed coffins. Mortuary objects included tools used in daily lifeand an abundance of jade ornaments Rich people were often buried with a lot of jade or ceramic items, and exquisite relics unearthed at theBeinan site were mostly found inslate coffins. Therefore, slate coffins have become the most important excavated relics thus far and serve to highlight the importance of the Beinan site.
5-4. Jade objects found at the Beinan site:Human- and animal-shapedearrings
Most jade items unearthed from the Beinan site were mortuary objects found in slate coffins.The mortuary objects fell mainly into two categories —ornaments and ritualistic objectsthat were made in the shape of daily tools. Ornaments included headdresses, earrings, necklaces, and armbands. Earrings were the most common item and the notched circular earring was the main type. There were also earrings in other shapes, including one that showed two men carrying an animal. That unique imagery has become the museum logo.
There were alsotool-shaped jade items such as spears, arrowheads, axes, hoes, hatchets, and chisels. Although they lookedlike daily tools, these Taiwan jade burial gifts were often very sharp, showing that they were specifically made for use as ritualisticobjects, rather than for any practical purpose.
5-5. Ceramics found at the Beinan site: Pottery pots with single handles
Ceramics unearthed at the Beinan site can be divided into those that belong to the Neolithic Age and those that belong to the Iron Age.According to different archaeological layers,Neolithic ceramics includedJomon pottery at the early stage and Beinan pottery at the late stage. There were not many Jomon pottery items unearthed, and the most well-preserved ceramics from that era were two round-bottomed pottery pots of the Dapenkeng culture. Most of the well-preserved plain potterypieces were mortuary objects found in slate coffins, which were typically round-bottomed pots with two vertical handles.
The Iron Age ceramics were more varied in shape and size. The bodies of such vessels were either conical or rounded, and they generally were equipped with smaller round bottoms. The handles were triangularin shape, and the exterior of the vessels was decorated with many different images and themes. Remnants of red paint were found on the surface of such vessels as well.
5-6. Architectural remnants at the Beinan site: Masonry ring
The BeinanArchaeological Site is a large-scale site of ancient human settlement that offers many architectural remnants.
The main unearthed architectural structure at the site belonged to the late stages of the Beinan culture–a Sanhe-type Beinan settlementabout 2,000 to 1,700 years ago. The architectural structure suggests that general accommodationsat the time were slightly rectangular and arranged consecutively, with the main axis pointing to northeast and the short side facing Dulan Mountain.
Each semi-crypt housewas small in size and had an interior inlaid with slate slabs. The exterior of the house had a slightly elevated outdoor aisle andthe ground was lined with drainage ditches. At the side of each house, there was a semi-crypt type ofstorageroom.Large and heavy stone stairs werepart of basic housing infrastructure.
