Pulosari (volcano)

Mount Pulosari is a stratovolcano in Pandeglang Regency, Banten, in West Java Indonesia. There are active solfataras on its 300 m deep caldera wall.

Geology
Pulosari is included on the list of 116 Indonesian Holocene age volcanoes. It has been identified as a volcano in a fumarolic state with no known eruptions. Basalt, andesite, and pyroxene have all been identified in the petrology of the mountain.

An 1875 account describes the crater as consisting of "tan lava and traohite chunks", around 800 steps in diameter and shallow. It also states that the crater contains boiling mud and that the rim is permeated by sulfurous gas made more prominent should the ground be punctured.

History
During the 10th century, a Hindu temple was built on the highland of the mountain, under the Sunda Kingdom. Five statues that share a single base depict Shiva Mahadewa, Durga, Batara Guru, Ganesha and Brahma; these are known as "Caringin" statues.

800 priests are said to have lived on the mountain under the leadership of Prabu Pucuk Umun during the era of Sunan Gunungjati and Maulana Hasanuddin of Banten in the 16th century. Hasanuddin lived there for almost a decade, and many converted to Islam. Those who did not left for the southern mountainous areas. Local history states that Hasanuddin required the converted priests to remain on the mountain, believing that a lack of pious guardians would be detrimental to the welfare of life on Java.

The stratovolcano has also been known by the name Poelasari and Pulasari. In The Book of Ancient Kings, Mount Pulosari is referred to as Mount Batuwara.

Cidaresi Bergores stone
At 06° 21' 39.5" S, 106° 00' 17.6" E stands the Cidaresi Bergores stone, a 175 cm long by 102 cm wide monolith with triangular shapes scored into the surface. Locally, the stone is called 'batu tumbung' or 'batu tum' because the triangles are representative of female genitals. The stone is composed of andesite and is located in the midst of rice paddies. It is considered a symbol of fertility.

Citaman pools
Sukasari Village stands at the base of Mount Pulosari and houses a complex of nine purification pools are located.

Cipanggitikan
The pool at Cipanggitikan has been covered by concrete, leaving a rectangular shape measuring 4 m by 5.86 m. It has a depth of 80 cm, and the water is used in the supply for Pandeglang and is owned in part by the Regional Drinking Water Company (PDAM) [id] in Pandeglang.

Cikajayaan
Cikajayaan is west of Cipanggitikan and means "water of glory". Locals believe bathing in the pool will bring success. The pool is square, bordered by small rocks, and had an area comprising 3.8 m by 3.8 m, with a depth of 53 cm. It is surrounded by Hibiscus rosa-sinensis.

Cikaapeusan
Approximately 10 m from Cikajayaan stands Cikaapeusan, known as the "water of bad luck". People bathe in the pool to get rid of their bad luck. It measures 4.80 m by 5.30 m with a depth of 70 cm, and is covered by concrete like Cipanggitikan, save for a small opening on one side.

Cipangantenan
Cipangantenan is approximately 8 m west of Cikaapeusan. It is in the shape of an "L", measuring 3.54 m by 2.90 m with a depth of 44 cm. This pool has a spring flowing directly into it that also flows into the larger Citaman Pool, and is surrounded by andesite rocks. The name means "wedding water" as it is believed that those who wish to find their "soul mate" must bathe in the water.

Cikapaliasan
Approximately 6 m west of Cikapangantenan, the waters of this pool are believed to protect from danger. The pool is shaped like a trapezoid and covers an area of 34.55 m square with a depth of 22 cm. The water from this pool flows directly into Citaman Pool.

Cikaputrian
The most popular of the nine pool, Cikaputrian measures 2 m by 2.4 m with a depth of 30 cm. It lies approximately 7 m to the northeast of Cikapaliasan.

Cikahuripan
Located to the left of the entrance to the Citaman site, the pool is bordered by andesite rocks and covers an area of 14.29 m square, with a depth of 60 cm.

Cikembangan
4 m southwest of Cikahuripan, Cikembangan – meaning "flower water" – is directly adjacent to Citaman Pool. It measures 2 m by 4.35 m and has a depth of 28 cm. It is covered with green moss.

Citaman
The largest of the pools, Citaman covers an area of 941.58 m square and a depth of up to 100 cm. The water flows directly into the Cigetir River. It has a divider, allowing for division between genders in using the pool. It is 175 m above sea level, located at coordinates 6° 25' 24.5" S and 105° 55' 09.8" E.

Goong complex
The Goong complex is approximately 30 km from the Pandeglang Regency government center. The word "Goong" is Sudanese for "gong" for the artifacts found among the megaliths. Several research studies were conducted to determine the cultural heritage of the site, concluding that the area is prehistoric and the stones are megaliths. It is located at coordinates 6° 20' 17.2" S and 105° 55' 18.9" E and is a terraced site, low on the west and high on the east. The resulting stepped contour is called Kaduguling Hill.

One of the megalith areas includes 12 stones in a cupola, one menhir surrounded by 10 cylindrical stones with flat tops and one gong shaped artifact. The formation is often referred to as a "meeting bracelet". There are five such constructions within the complex.

Ranjang stone
The flat-topped andesite stone located at Batu Ranjang [id] is known as a dolmen. Though these are traditionally grave sites, this particular location is thought to have been used for the worship of ancestral spirits.

Sirit Gopar site
On the slopes of Mount Pulosari at 6° 19' 20.4" S and 105° 58' 52" E stand a number of menhirs in the shape of a phallus. The name of the site translates to "male genitals". It is considered a site for fertility rites from prehistoric Indonesian peoples.

Tongtrong stone
The Tongtrong stone is located in the yard of a prayer room, and because it has been removed from its historical context, its exact historical cultural function is unknown. There is debate as to whether it was involved in burial or, because of its shape resembling female genitals, in fertility ceremonies.
