Where was Tempest shot? Revisiting key filming locations of the Korean drama

As mentioned, Tempest filming was centered around South Korea, mainly Seoul. The production aimed to shoot on real locations rather than relying on CG or studio sets to get the city's realistic and raw feel. Many reports and social media posts from 2024 confirmed Seoul to be the base of the shoot. The city offers a perfect urban skyline along with some government quarters and localities for diplomats, setting up the perfect backdrop for the spy thriller show.

Along with Seoul, the production utilized several other locations, such as Songpa-gu and the Lotte World Tower area. This served as the location for some establishing shots and outdoor scenes with luxury hotels, restaurants, aquariums, and the tallest skyscraper forming the backdrop.
Some reports have also spotted another location from Paris, France (Rue de Tilsitt near Arc de Triomphe) in the trailer. This suggests that the story has some international intrigue as well.
Daejeon offered a landscape for both the spy as well as the romantic scenes in Tempest

Next is Daejeon National Cemetery in South Korea. The place has also been featured in the trailer. It is known for a distinct memorial tower and ceremonial plazas. It also has tree-lined axial avenues, perfect for some romantic moments to be shot under the view. The memorial serves as the resting place for many veterans of South Korea, emphasizing the political assassination storyline of the show.
The trailer also features a gunman shooting their target against the backdrop of a beautiful city's night skyline. All of this has been shot in Busan, where skylines, bridges, and harbor views are consistent and form the character of the city. South Korea's busiest port adds some international thriller atmosphere, highlighting the scale and quality of the show.
On March 25, 2024, the filming of Tempest began, with the cast actively posting on social media about being in Seoul by the summer. September 10 is when this show premieres. If you are into some spy drama, this could be your next watch, fresh on the list.
