																							| Literally meaning either “false” or “unreal mountain,” gasan was an important
																								element of the traditional Korean garden conceived by connoisseurs who wanted to condense a large natural landscape into their
																								garden. The “mountain” was sometimes made with earth dug to make an artificial lake or pond in a royal palace. We can see an
																								example of this in the work by Amisan of Gyotaejeon (Hall) and the tiny island on the lake of Gyeonghoeru (Pavilion) in
																								Gyeongbokgung (Palace). Gasan was also developed in an effort to increase the life energy (“gi”) of a site according to pungsu
																								(or feng sui) principles. The founders of the Joseon dynasty, for instance, created an artificial mountain within the
																								precincts of the Royal Shrine of Jongmyo in an effort to supplement the weak land energy in front of the shrine. |  |

																																| Records show that there were two “man-made mountains” around Ogansumun, one in the south and the other in the north
																																	of the Cheonggyecheon waterway. The mountains were made during the 1760 dredging work with earth and sands dredged
																																	from the Cheonggyecheon. When the dredging started, Cheonggyecheon had been filled up with drifts that raised the
																																	riverbed almost to the same height of the embankments built on both sides of the waterway. Dredging was not an easy
																																	task, of course, but a more difficult question was how to deal with the huge amounts of dredged earth and sand.
																																	Without efficient means to remove the silt, they relied on any expedient means that could be found. One idea was to
																																	fill in sunken roads and low-lying land around the area but most was left heaped up wherever there was space. 
 As the project neared completion in April, King Yeongjo requested a report about the dredging work from a
																																	senior minister named Yu Cheok-
 |  |  |  
																										| gi (1691-1767). In the report, Yu said that the dredged silt should be removed to a distant place even if that meant
																											spending a lot of money. The king accepted his advice, and the result was the creation of two huge mounds erected outside
																											both banks on both sides of Ogansumun. Most old maps published after 1770 clearly show the two large mounds at both sides
																											of Ogansumn with names gasan (“false mountain”) or josan (“artificial mountain”). 
 |  
																										| These mounds were in fact nothing but loosely piled silt, which continued to grow with each dredging project that followed.
																											Then the hills began to collapse, finally turning themselves into gently sloped hills where people came to plant tress and
																											flowers. When the authority gave new names to the districts of Seoul in 1914, the area was named as Bangsan-dong (“district
																											of floral mountains”) because of the sweet fragrance of flowers filling the air around the mounds.

																																| With The increased population of Seoul combined with the currents of modernization
																																	the historic heritage of gasan gradually vanished. The gasan in the north was heavily damaged in 1898 where a tramcar
																																	house was built on the site. The other in the south was damaged when the Joseon School of Medicine was built in 1918
																																	and then the Gyeongseong Teachers College in 1921. Earth from the mounds was used for the renovation of roads in the
																																	Jongno area. Today, the site of the southern gasan is occupied by Pyeonghwa Market in Cheonggyecheon 6-ga and the
																																	National Medical Center in Bangsan-dong while the site of the northern gasan by the Dongdaemun Shopping District. |  |   |  |
