Historical value

Non Nuoc Cao Bang Geopark is also land of many tangible and intangible cultural heritage sites, especially historical monuments, of which there are two Special National Monuments: Pac Bo, where President Ho Chi Minh lived and worked the early days to lead Vietnam’s revolution.

The main historical relics consist of Pac Bo, Coc Bo, Bo Bam Cave, Lenin Stream, Karl Marx Mountain, Co Rac Ground and Khuoi Nam. The famous Coc Bo Cave is where President Ho Chi Minh established his residence and worked on Vietnam's revolutionary course after spending 30 years abroad to seek ways to liberate the country.

Inside the cave there is a wooden board which was used as a bed for Uncle Ho. In this place, Uncle Ho, in the simple dress of the Nung ethnic group, sat by the fire at night to discuss with his assistant Pham Van Dong, Vo Nguyen Giap and Phung Chi Kien on the situations at home and abroad.

It was also where the great leader predicted: "In four or five years, the Vietnamese revolution will be successful," which was proven true, since four year later, on September 2nd, 1945 the Democratic Republic of Viet Nam, the first State of workers and peasants in Asia, came into being.

Located around 1km from the mouth of Pac Bo Cave, there is a small shack by the side of Khuoi Nam Mountain. In this shack Uncle Ho held the eighth Party Central Committee Meeting, which promulgated a resolution on preparations for the armed insurrection and the establishment of the Viet Minh and the revolutionary war zone. Adjacent to the shack is milestone 108 marking the Viet Nam-China border, where Uncle Ho bowed to kiss the beloved land of his country, after many years living abroad.

Most of the caves are developed laterally and are of considerable size. An outstanding feature of the caves is the extensive and well-preserved system of speleothems decorating the cave ceilings and walls.

Among the total of 400 caves surveyed throughout Vietnam, Cao Bang has 12 of the 30 longest caves (1km to 19km long) including: Nguom Sap (5379m), Ban Ngam (3600m), Nguom Nam Lao (3360m), Ki Lu (3353m), Pac Bo (3248m), Pac Lung (3109m) and Nguom Ngao (2769m).

Some 200 caves have been identified in Cao Bang by various Vietnamese expeditions and those of other countries such as France, Italy, UK, Romania, and the USA (Howard Limbert, 2003, 2005; Geokarst, 2012, 2015).

Of these, 50 caves have potential for tourism development, such as Nguom Ngao, Ki Lu or Doi. However, most of them have not yet been opened to tourists, so there are many future possibilities./.
