→ The Geunjeongjeon Platform — The 12 stone markers around the throne hall platform represent directional deities. Officials stood behind the marker corresponding to their rank — the highest ministers stood on the north side (facing the king), while lower officials stood further from the centre.

→ The Gyeonghoeru Pavilion — The pavilion sits on 48 stone pillars in the middle of an artificial pond. The pillars are stone replicas — the original wooden ones rotted and were replaced in the 1860s reconstruction. The pond was designed to cool the pavilion in summer through evaporative cooling.

→ The Hyangwonjeong Pavilion — A hexagonal pavilion built on an artificial island at the north end of the palace grounds, connected to the shore by a bridge called Chwihyanggyo. The bridge was the original wood structure from 1873 until it was replaced with a concrete copy in 1953 after war damage.

→ The Injeongjeon Ceiling — The throne hall's ceiling is decorated with two golden dragons. The ceiling is lower than Gyeongbokgung's equivalent — a deliberate design choice that made the king appear taller when seated on the throne by compressing the vertical space around him.

→ The Buyongjeong Pavilion — In the Secret Garden, this square pavilion sits on an artificial island in a rectangular pond. The pond was designed as a mirror: scholars sat inside the pavilion to read, and the reflection of the water was meant to symbolise the Confucian ideal of self-reflection.

→ The Nakseonjae Hall — A 19th-century addition built for a royal concubine, this hall shows Chinese and Western influences in its window design — the only palace building in Seoul with rectangular window panes rather than traditional paper screens.

→ The Spirit Tablets — Each king and queen's spirit tablet is a simple wooden block, stored in a separate alcove (gambang) with a sliding door. The 49 alcoves in Jeongjeon and 34 in Yeongnyeongjeon hold tablets of different sizes — the oldest are the smallest, following the Confucian principle that modesty increases with wisdom.

→ The Stone Paths — The courtyard has two raised stone paths. The higher central path was used only by the king; the lower side path was for the crown prince and officials. Between them, the unpaved sand surface was where the musicians and dancers performed during the ritual — their footprints in the sand were read as omens.

→ The Eave Projections — The hall's eaves extend 3.5 metres from the walls without any supporting pillars on the ground floor. This cantilever system, achieved through complex bracket joinery, protects the paper doors from rain while keeping the view unobstructed from inside.

→ The Roof Tile Patterns — Hanok roof ridges end with decorative tiles called mangdol. Each neighbourhood block used a slightly different pattern — a visual address system for delivery workers and officials before street numbers existed.

→ The Ondol Vents — Look at the base of exterior walls for small stone vents. These are the exhaust ports for the ondol underfloor heating system: smoke from the kitchen fire passes under the stone floor through flues, warming the entire house from below.

→ The Gate Hierarchy — The size and ornamentation of each house's main gate (daemun) indicates the owner's social class. A gate with a tiled roof and raised threshold meant a yangban (aristocrat) residence; a plain wooden gate without a threshold meant a commoner household.

→ The Bell and Signal System — A large bronze bell hangs in the upper storey. During the Joseon period, it was rung at dawn to open the four main gates and again at dusk to close them — the bell's sound was calibrated to carry exactly to the city walls.

→ The Stone Joint Marks — The granite blocks of the base are marked with carved Chinese characters — masons' signatures from the original 1398 construction. When the gate was rebuilt after the 2008 fire, reconstruction teams added their own marks in the same style on the new stonework.

→ The Stone Pagoda — A seven-storey stone pagoda from the Goryeo period stands near the main hall. Unlike the wooden temple buildings that have been rebuilt multiple times, this pagoda's granite blocks are original — the stone has weathered smooth after 800 years of monsoon rain.

→ The Temple Stay Programme — Bongeunsa was one of the first Korean temples to offer overnight temple stay programmes for foreigners. The programme follows a schedule that has not changed in centuries: waking at 4:30 AM for dawn chanting, followed by shared chores, meditation, and tea ceremony.

→ The Junghwajeon Hall — The throne hall's interior ceiling is the only Joseon palace ceiling decorated with the four-clawed dragon of the Korean Empire rather than the seven-clawed dragon of Ming China — a subtle assertion of imperial sovereignty after Gojong declared Korea an empire in 1897.

→ The Western Garden — Unlike other Korean palaces with traditional pungsu gardens, Deoksugung's garden was designed in the English landscape style with lawns, flowerbeds, and a fountain — reflecting Gojong's embrace of Western aesthetics during the Korean Empire period.
