Daejeon Observatory offers opportunities to observe celestial bodies. This observatory is the first of its kind in terms of accessibility for ordinary people to enjoy astronomy. Observation of the sun can be made during the day, and the observation of other celestial bodies such as planets, nebulas, and clusters of stars at night.
It's a cool place to go if you have even a little interest in space and the stars^^
