There are already lots of reviews about the sites. But if there is interest I can add a few. What sites would you be interested in reading an additional review? I would lean towards covering one with "only" 3 reviews or a tent site.

I would personally be interested in 5 reviews, all of which can provide information specific to your visit that many others have not commented on or have not experienced.

World Heritage Sites (3)

Gochang, Hwasun, and Ganghwa Dolmen - Only 1 reviewer mentioned the Hwasun Dolmen site. Of the 3 dolmen clusters, this is the one I have not visited.

Baekje Historic Areas - You are the first reviewer to visit Mireuksaji, after its full re-assembly, thoughts?

Namhansanseong - How much of the wall did you actually hike? Did you go to the ruined outer wall?

Tentative Sites (2)

Southwestern Coast Tidal Flats - No reviewer has mentioned any other site besides Suncheon, what was your impression of the Gochang tidal flats? Being Korea's nomination for 2020, it would be nice to hear more about the other serial components.

Stone Buddhas and Pagodas at Hwasun Unjusa Temple - Currently a topic on the Top Missing List, is this the best cultural site remaining on Korea's Tentative List?

I will get to work then :)

Reviews are in the pipeline. I did not do Namhansaneong, as I cant really addsomething new. I walked from the North Gate via the South Gate to the East Gate. So I left out the ruined part.

Stone Buddhas and Pagodas at Hwasun Unjusa Temple (100% rating based on 3 votes)

Based on the two reviews, I am starting to wonder if this site has an outsiders chance to squeeze into one of the final positions for the Top Missing! Considering how well represented Korea is, it probably won't make it though. When thinking about what is "missing" in Korea, I kept my proposals to a minimum because, well Korea has 14 world heritage sites! I learned quite a bit about Unjusa since its inclusion on the Tentative List, thanks in no small part because of both of your reviews. This is one of the last major cultural sites in the country and I will have to travel to Hwasun during my next visit.

"It would also be Korea's best world heritage site." - Philipp

"I spent around two hours exploring all the pathways and admiring every single statue and pagoda." - Philipp

"Unjusa Temple might be one of Korea's most amazing cultural tourist spot." - Zoë

"Beyond the temple are paths to more statues so don't turn back just yet." - Zoë

Updated Korean Tentative List 11/15/2020 - 4/15/2021 [Expected/ Not Guaranteed]

After 10 years, Korea seems on the verge of an updated tentative list (large or small is anyone's guess). Numerous symposiums have been held for aspiring nominations between 2016-2020. Several nominations have been submitted to the Cultural Heritage Administration between 2018-2020, most were rejected (my count is 7 rejections) with recommendations not dissimilar to ICOMOS 'not inscribe' evaluations. These rejections are not permanent and most seek to resubmit based on provided recommendations.

Is this a guarantee that a new tentative list will emerge, hardly. It may just be a select few sites are approved or none at all. It is very easy to find information on aspiring nominations in Korea and the Cultural Heritage Administration make their meeting notes public, making it convenient to see when nominations are approved or rejected. A handful of important "World Heritage" Meetings are scheduled over the next few months. For aspiring nominations, the magic words to type in "Google translate" are 'UNESCO Provisional List'.

*Application Rejected by (CHA), plans for re-submission

The Seoul City Wall (Hanyangdoseong) nomination may be expanded to include the Northern fortifications (Bukhansanseong) that protected pre-modern Seoul. This expansion would effectively double the length/size of the nomination from 12km to approximately 24km of intact protected fortifications, including part of Bukhansan National Park.

"Currently, the government is pursuing a comprehensive research, such as a plan to link Bukhansanseong and Hanyang City as a continuous heritage, and the results are expected to be seen by next year." November 2020

Moreover, the government is opening all remaining sections of the Seoul City Wall between November and this coming Spring, making a proper circumnavigation (without any detours) possible for the first time. There are plans in the works to better connect trails from Seoul City Wall with Bukhansanseong (about 5 kilometers apart), which really would add a special element to this hiking course connecting Seoul with Bukhansan National Park. Lastly, a section of the fortress around Namsan Mountain in central Seoul is now open as an archeological site. Much of this section of the fortress was largely destroyed in the 20th century, a Japanese WWII bunker is located here and the ruins of the Chōsen Shinto Shrine.

"Off-limits No More" Korea JoongAng Daily (English)

"Walking from Seoul's first park to northern city gate that overlooks Seoul" The Korean Herald (English)

"Seoul reveals traces of old Hangyang" The Korean Herald (English)

"More Mt. Bukak trails to be opened to citizens: Cheong Wa Dae" Yonhap News (English)

This expansion plan seems logical to me, since much of the fortification to protect Seoul on view today (both Hanyangdoseong and Bukhansanseong) are from Sukjong of Joseon's large-scale re-building or expansion project of the Capitals defenses between 1704 and 1714. Perhaps this nomination is reconfigured for a new submission for 2023, though that requires rapid development of a complete nomination file by January 2022. If Naganeupseong Village is not ready, the Hanyaongdoseong dossier just may fill the slot for 2023, or both nominations might look toward 2025.

I think overall expand the WHS Namhansanseong to include Bukhansanseong and whole city wall as Seoul Defense System, maybe easier move. It will be quite strange to list Southern defensive fortress separate from Northern and central fortress.
