History & Culture Restoration

Insistences of organizations involved on how to restore historical/cultural sites and remains

On how to restore Gwangtonggyo	Seoul Metropolitan Government	- To restore it on a place a little closer to upstream from its original location, considering practical convenience
	Citizen's Committee	- Ditto - Some members insisted on re-placing the real one at its original location.
	Cultural heritage experts (from their meeting on July 15th, 2003)	- It is difficult to re-place the real one at its original location. It is necessary to discuss about it more with some experts.
	Civil organizations	- To re-place the real one at its original location
On how to restore Supyogyo	Seoul Metropolitan Government	- To build a replica at its original place instead of moving the real one from where it was stored, i.e. Jangchungdan Park
	Citizen's Committee	- To place replicas of the stone rails of the real one on one of the bridges nearby as a symbol of its past existence, as there are some difficulties to re-place the real one in its original place due to the differences in dimensions with the site. - Some members insisted on re-placing of the real one at its original location.
	Cultural heritage experts (from their meeting on July 15th, 2003)	- It is desirable not to move the real one from its present location, as there is a risk of some damages and to place a replica at its original location.
	Civil organizations	The piers of the real one are likely to interrupt the water flow in rainy days during summertime. It is expected that more than half of the members will get harmed, if an attempt to move it from its original location is made.
