Incheon is located in the central part of the Korean Peninsula and has been considered very important area as archeological value as well. It has been a region which Korean government and some Archeological organization have had a great interest in from 20th century, but on the contrary to these national concern, few research on these area has made progress until now. Particularly, specific research on Prehistoric study has begun since 1990s. Here are some results on Gyunggi-Bay described below: First, there are Paleolithic Sites were found in the Yellow Sea coast around and hillock at about 15 spots. Of these 15 spots where Paleolithic Sites are, sediments in Bullodong(불로동) Sites show following results through chronical measure ; 26,150±380 b.p and 23,750±230 b.p. Second, A Neolithic study about Gyunggi-Bay is closely related to natural environment. Gyunggi-Bay is composed of a number of islands, and relics are mostly found in hillock, sand beach, sand dune, sand bar and so on. And as this area has well developed tidal flats, which was used for living area of neolithic men, there is a substantial possibility that dugouts may be found. Also, it has 12~32‰ of salinity, which is suitable for growing oysters, and as a result, shell mounds range widely in this bay. Third, Shell Mound in Neolithic Age Sites are divided into 3 types. Of 3 types, Nae-man(內灣) type is found in the Yellow Sea Coast. Shells which are in Yellow sea coast have only one quarter so many kinds as varieties of East Coast Shell and are included in Crassostrea gigas. This result indicates that it is pretty proper climate condition for an oyster to live in Yellow Sea Coast. Fourth, some housing lots and Stone Coffin of Bronze Age sites, were found in coast and hill area as; housing lots have rectangle shape and clay bottoms. In remains, there are various kinds stone tools included Plain Coarse? Pottery. One of them, Discoidal Mace, Shows that Complexity Society had appeared in Incheon as a symbolic meaning of remains. Stone Coffin is rectangle and have single valve stone, which is date to the 7th to 8th century BC.
