Castle Lantern – Seonggwakdeung

The Castle Lantern (Seonggwakdeung) is a participatory lantern experience inspired by the “Gakjaseongseok”—engraved stones that symbolize the real-name construction system used when building ancient city walls. Crafted from semi-transparent and transparent PP material, the lantern allows citizens to write their wishes or messages and stack them like stones, creating a collaborative lantern fortress.

To recreate the authentic look of a stone wall, the lanterns come in three different stone-inspired colors. For safety and stability, the pieces are designed in an interlocking "LEGO-style" structure.



The back of each lantern is designed to accommodate a lighting line, but the true highlight has always been the creativity of participating citizens. The diversity of designs—from heartfelt messages to charming illustrations—transformed the experience into a collective visual diary, offering moments of deep joy and emotion. Once completed, the Castle Lanterns form a structure approximately 10cm tall, 18cm long, and 9cm wide, and have been popular enough to be displayed at Seoul Citizens Hall even after the event ends.

How to Use the Castle Lantern

    • Then, fold along the pre-cut lines.

  2. Once folded into a rectangular shape, locate the four holes on the top panel.

  3. Insert the circular connectors into the holes by twisting them into place.

  4. At the event site, go to the castle frame and connect the lantern to the structure by hooking the wire on the back side.

The Golden Axe and the Silver Axe

The Golden Axe and the Silver Axe is one of Aesop’s fables, and it is also known by the title Hermes and the Dishonest Woodcutter . This tale is often staged as a scene in which a mountain spirit appears and presents a golden axe and a silver axe. Long ago, in a remote village deep in the mountains, there lived a kind woodcutter. One day, while chopping wood, his hand slipped and his axe fell into a pond. As he stood there, troubled and distressed, a mountain spirit appeared and asked what had happened. After hearing the story, the spirit rewarded the honest woodcutter by giving him both a golden axe and a silver axe as gifts. When a wicked woodcutter heard the news, he came to the same pond and deliberately dropped his own axe into the water. When the mountain spirit appeared again, the wicked woodcutter lied. In the end, he could not even get back his iron axe.

Baekje’s Government System and Attire

Baekje was a kingdom founded in 18 BCE by King Onjo. Building its foundation on the fertile natural environment of the Han River basin, the kingdom grew and flourished, reaching its peak under King Geunchogo. Baekje cultivated a refined and elegant culture, but it fell in 660 CE to the allied forces of Silla and Tang. According to legend, Onjo, the son of Jumong, moved south and established the capital at Wiryeseong in the Han River region, first naming the state Sipje . After the death of his brother Biryu, Onjo united the people under his rule, and the name was changed to Baekje , meaning “a hundred joys,” symbolizing the people’s contentment in following him. Baekje’s governmental system developed into the office of the Sangjwa-pyeong (chief minister), the Six Jwapyeong, a 16-rank hierarchy, 22 Dammno (local administrative districts), Bangnyeong, and 22 central ministries. As depicted in Goguryeo murals, attire consisted of jackets reaching down to the waist paired with trousers, a...
