Arthdal Chronicles is one of the most expensive Korean dramas made in recent years and the following video is testament to where a lot of the money went. If you are visiting Korea and would like to experience Asadal/Arthdal for yourself, then you can go to the 10 million dollar set that was built special for the drama.
The set is located in the city of Osan, which is in Gyeonggi Province. It is also not going anywhere, because it appears that they are making it a permanent tourist attraction for anyone who wants to experience what it would be like to live in the times of Arthdal. there is even a small museum on site that explains the main characters of the show and what the show is about including how they made the set.
The video below walks us through the entire set on the main roads of Arthdal and, if you keep watching to the end, you can see the small museum near the entrance to one of the huge buildings. It is free to visit, so if you want to visit the set then you can until November 8th. Opening hours are from 10am to 5pm and you can have a guided tour as well. There are 20 people to a tour. Weekdays are open to visitors, but you must have a reservation on the weekend.
