We report the results of our study for ascertaining whether Ganui-dae built in the Josen Dynasty actually performed an astronomical role or not. The Ganui-dae was the first astronomical structure built as a part of the state astronomical undertakings by King Se-Jong. Our analysis was based on the Annals of the Joseon Dynasty. At first we extracted the records regarding Ganui-dae from the Annals of the Joseon Dynasty and then classified them under six heads according to their astronomical meaning and historical significance. From this analysis we found that the Ganui-dae performed the actual astronomical role. In addition, the provisional offices and peoples mentioned in the records show the astronomical correlation. Generally, when taking into account the functional side of the records, the Ganui-dae was related with the observation. Therefore, the Ganui-dae was the space for the astronomical activity. In conclusion, the Ganui-dae was built for the purpose of the astronomical activity.
