| Research Abstract |
At the sites of the lmperial palaces and the government officies they were reconstructed or build on the base stones often. Then they differ widely in that shrines are reconstructed each twenty years. The imperial palaces and the government officies have poor historical materials so we doesn't exactly decide life-time of them. To servey the term and transition of the sites, they were for about 100 years from sites, the latter half of the 7th century to the latter half 8th century. Many sites were rebuild three or four times, so they had the term for 25 years or 30 years. Having some questions, to conclude, lifetime of structures is more than 25 years and 30 years.
The case of Ise shrine, we got the data to have been for about 35 years. These data of shrines and palaces are very close, then we conclude the lifetime of embedded-piller buildings.
