Ganghwa-do    강화도
Korea's most historic island,
with several sacred mountains
Ganghwa-do is a County of Incheon City and Korea's fifth-largest island, at 305 sq km (422 if you
count all the smaller islands around it).  It sits right at the mouth of the Han River, separated from
the Gimpo Peninsula by only a narrow channel -- through which the water can be quite treacherous
-- two large and busy bridges now span it.  Due to its strategic location it was the site of a prehistoric
civilization and great events in two different parts of Korea's history, and has been the site of several
nationalistic religious cults; therefore there are many historical relics and significant cultural sites on
this beautiful island, which has led to it becoming one of South Korea's leading second-level tourist
destinations.  It's also one of the three counties famous for growing plenty of
insam, Korea's high-
quality ginseng, along with Yangyang and Geumsan.  The northern coast of the island faces the
Hwanghae-do Province of North Korea across the Han River estuary, and thus is heavily militarized;  
civilians are rarely permitted to visit, with prior arrangements.

Ganghwa-do contains a few dozen dolmens
(prehistoric raised-up uncut boulders, mostly assumed to have
been tombs and altars)
from the 1st millennium BC, now registered with UNESCO (along with those in
Gochang & Hwasun)
as World Cultural Heritage Sites since 2000.  It was also the site of battles
between Korean defenders and French and American attackers in the late 1800s, and so has
several fortresses with various military relics and displays.  Neither of these historical treasures
on Ganghwa are of much interest for the main themes of this website, however; they are well-
covered elsewhere -- start with the
official County English website.

Much more interesting for my purposes is that the Goryeo Dynasty royal court fled here for shelter
from the invading Mongols in 1232, staying for 38 years, during which time the 81,000
printing-woodblocks (one of Korea's greatest treasures, another of its UNESCO World Cultural
Heritage Sites, now stored at Gaya-san Haein-sa) were carved.  Remains of the temporary royal palace
and the Ganghwa Town Fortress around it
(rebuilt many times since then) can be found, and the steep
craggy mountain just west of town has come to be called Goryeo-san due to the wealth of relics and
sacred sites from that era
(and a fascinating Buddhist legacy from even before that) on and all around it.  
In addition, Mani-san in the island's southwest corner has been a site of Shamanic worship since
ancient times, becoming strongly associated with the cult of
Dan-gun Wanggeom, Korea's mythical
founding-king -- that connection has now spread to neighboring mountains.  Hyeolgu-san (just to
Goryeo's south) has also become regarded as a highly-sacred mountain, and Bomun-sa Temple on
another island just off the West Coast has developed into one of Korea's eight special shrines for
worship of the Bodhisattva of Compassion.  All together Ganghwa-do has become a very interesting
place for the study of Korea's religious history and the modern revival of its indigenous spiritualism.

One theory holds that Mani-san represents Heaven, Goryeo-san represents Earth and Hyeolgu-san
in between them represents Humanity -- and therefore Mani-san is the Father, Goryeo-san is the
Mother and Hyeolgu-san is the Child they hold -- echoing the famous first line of the world-famous
Western Inscription" by Chang Tsai (Zhang Zai, 1020-1077, Song Dynasty China):
"Heaven (
yang) is our Father; Earth (yin) is our mother;
and I, this tiny thing, live comfortably enfolded in Them."
Ganghwa-do contains no less than five sacred mountains,
decorated with a wide variety of wonderful cultural treasures,
all forming the end of the Hannam-jeongmaek Branch of the Baekdu-daegan:

Goryeo-san       (436m)  (northern Ganghwa-do)
(including Byeollim-san 400m & Bongcheon-san 291m)    Site of several important Buddhist temples
(Jeokseok-sa, Cheongryeon-sa & Baekryeon-sa) and Shamanic shrines including the large new
dang of "National Shaman" [Gukmu] Kim Kum-hwa, one of Korea's most famous Manshin, and
a variety of Goryeo Dynasty relics associated with various legends
(including a fortress & royal tomb),
and several of the greatest
Goin-dol or Dolmen of ancient proto-Korea.

Hyeolgu-san       (466m)   (central Ganghwa-do)
(including Toimo-san 339m)  
Site of several interesting Buddhist temples (Hwangryeon-sa) and Shamanic shrines, featuring
a new
Dan-gun Seongjeon [Saint-Hall shrine for Korea's Founding-King].

Mani-san       (469m)   (southwestern Ganghwa-do)
(including Sang-bong 255m, right next on the coast)    Site of the Chamseong-dan [Truly Holy Altar],
an ancient stone shrine on one peak that commands a wide view of the Yellow Sea,
associated with King Dan-gun.  The "Demon-Expelling Mountain" also features a special
shrine for Dan-gun and other national heroes, Jeongsu-sa Temple and other sites.

Jeongjuk-san       (200m)   (southeastern Ganghwa-do)
site of Jeondeung-sa Temple; can be considered an eastern extension of Mani-san

Sangbong-san       (316m)    (on Seokmo-do Island just west of Ganghwa-do).
(including Haemyeong-san 309m)    Site of Bomun-sa [Treasure-Gate Temple], one of Korea's eight
special shrines for the Bodhisattva of Compassion
(due to a carving of him on the “Eyebrow Cliff”).
