This historical marker indicates that this area was once known as Tangchundae. Tangchundae was located around the current Segeomjeong Elementary School area, and was named for its spacious and flat terrain. Since the Silla period, there was a Buddhist temple called Jangeuisa here, and during the early Joseon period, scholars were granted a form of sabbatical to study in this area. It is also known as a playground used by Prince Yeonsan, infamous for his tyrannical behavior. Prince Yeonsan engaged in immoral activities with palace ladies here and ultimately faced his downfall. Perhaps due to this history, King Yeongjo relocated Chongyungcheong, which had been responsible for military affairs in this area, and changed the name from Tangchundae to Yeonyungdae, symbolizing its military significance.

By the way, following the Japanese Invasions of Korea between 1592 and 1598 and the Second Manchu Invasion of Korea in 1636 during the Qing Dynasty, King Sukjong developed a strong interest in the defense of the city wall, Hanyangdoseong, or the Seoul City Wall. Above all, having experienced two wars, King Sukjong came to believe that it was not desirable for a king to flee but thought that he should fight alongside the people of Hanyang. So, he decided to reconstruct the fortress on Bukhansan Mountain, which had previously been an earthen fortification, and fortify it with stone walls. During this period, the soldiers of Bukhansanseong Fortress built a storage facility for military provisions in the south of the fortress, which was named ' Pyeongchang’, that's right. The name ‘Pyeongchang-dong' has its origins in this place.

However, with Bukhansanseong Fortress to the north and Hanyangdoseong to the south, it left ‘Pyeongchang’ vulnerable to external threats. So, there was a need for an additional fortress to protect the valuable food storage. To address this issue and establish a connection between Hanyangdoseong and Bukhansanseong Fortress, a new fortress was built, which is the fortress known as Tangchundaeseong Fortress, named after this place, Tangchundae.

After the January 21st Incident, significant changes occurred in this area.

Also, the northern part of Jongno, which is the current Baegak area, experienced transportation problems, making it difficult to receive external support. That's why plans were made to construct roads in the Baegak and Inwangsan Mountain area to ease the movement of many people. It marked a significant change in mindset. We came to realize that attempting to enforce strict control to protect Cheong Wa Dae was actually leading to more problems.

Here we have the path known as the 'Bugak Skyway,' originally named Bugaksan Road. 아, The original name of Bugak was Baegak. Bugak Skyway is a path that starts at Changuimun Gate and passes through Baegak, connecting to Jeongneung and Miari. During its construction, Inwang Skyway was established, linking Jahamun Gate to Sajikdan Altar, which is now known as Inwangsan Road. It's a road that allows you to enjoy the scenic beauty of Seoul. Midway along the Bugak Skyway, they even built octagonal pavilions, creating an unexpected tourist attraction for the people of Seoul. They also significantly widened the once narrow and winding Segeomjeong-ro and developed the Pyeongchang-dong area.

At that time, this area was quite remote and desolate after sunset, which is hard to imagine now.

Now, our next destination is just a short walk away. You'll find a small park with a marker, and this is where Jojiseo used to be. There's a small milestone here.
