Altar architecture is a kind of sacrificial building, mainly formed in altar. Central architecture of Altar architecture is relatively simple. However, various attached building are necessary for worship. Among them, Sinsil which is a place to seal a God’s tablet, is very important.
The central government of the Joseon Dynasty attempted to define the local sacrificial system and make it customary as a way to strengthen the centralization based on Confucianism. Nonetheless, the altar architecture of the province without detailed regulations, were managed and underwent repairs according to the political situation of the state and local circumstances.
Sinsil, which is an important component of the altar architecture, best reflects this situation. Therefore, it was possible to grasp the situation of the altar architecture of the province in the Joseon Dynasty by analyzing the Sinsil through various documents. As a result of analysis, it was divided into six types. In addition, It is also found that there are temporal relation between these six types.
