Monte Brasil is the remnants of a tuff volcano (and peninsula) connecting the south coast of Terceira in the central Azores, overlooking the city of Angra do Heroísmo. Monte Brasil is flanked by two bays: the Bay of Angra (named for the city) to its east, and the Bay of Fanal to its west, and was used as a defensive point during the history of Angra, resulting in the construction of various forts and redoubts, including the Fortress of São João Baptista overlooking the city. ==History== The formation of Monte Brasil was the result of various eruptions of the Guilherme Moniz volcano, a large central volcano on the island of Terceira, this difficult to identify owing to subsequent eruptions and lava flows.〔França et al (2003), p.31〕〔Nunes (2000a/2000b)〕 Although this structure is eroded, there is considerable evidence of its influence, including, specifically: * a number of trachyte domes and basaltic eruptive centres around the interior; * two Surtseyan cones: Monte Brasil and the Cabras Islets; and * several ignimbrite deposits, including the Castelinho, that range to 23000 years of age.〔〔França (1993) and (Self, 1973)〕 An undated human presence on the mount includes artificial cavities located along the hill to provide shelter, but with little vestiges of formal use.〔 Although the those on Pico do Zimbreiro are vacant, similar spaces on the roadways to the caldera and ''Caminho das Belas-donas'' have bunks along the interior walls.〔 Another grotto on the roadway that skirts the Fort of São Diogo indicates its use as place to collect and store water, including channels, taps and reservoir.〔 Some specialists have speculated that these cavities have been created by ancient cultures, e.g. Phoenicians.〔(【引用サイトリンク】url=http://www.ancient-wisdom.co.uk/portoazores.pdf )〕 These chambers are not suitable for habitation but could be used as simple structures for Phoenician shrines. Such discovery would testify the presence of ancient cultures in Azores long before Portuguese. There are offered also other explanations, e.g. chambers were created in medieval times for the needs of military or agriculture. At the end of the 16th century (around 1590), Monte Brasil was occupied by an estate/farm owned by Manuel do Rego da Silveira and several fortifications, including the Forts of São Benedito and Santo António (towards Angra) and the Fort of São Diogo (in the direction of the Bay of Fanal).〔VPR (23 October 2013), p.8〕 The existence of reservoir and staircase, in addition to springs already identified in the 16th century cartography, reinforces the importance of Monte Brasil during this time.〔 From this point forward many of the rock deposits (boulders/rock) from the volcano's submarine eruptions were used in the construction of the forts and defences along the coast of the islands.〔〔França et al (2003), p.77〕 Writing in his epic tome ''Saudades da Terra'', the humanist theologian Gaspar Frutuoso, while describing Angra: :''"...what makes it very beautiful, the great high mount called Brasil, as I mentioned, it is all covered in pasture, some farming (which had been covered in trees)...encircled on all four sides, two small two large, this a caldera"''.〔 Between the 16th and 17th century, the construction of a system of fortified structures that would be the nucleus of the Fortress of São Filippe/São João Baptista do Monte Brasil.〔〔SRAF (1989)〕 Its main fortification hugs the northern slope of Monte Brasil, but includes of redoubts, emplacements and garrisons around the flanks of the volcano, including the Fort of Zimbreiro, Fort of Santo António, Fort of São Diogo and Fort of Quebrada.〔 Many of the road accesses to Pico do Facho, Pico das Cruzinhas and Pico do Zimbreiro, in addition to the caldera and coastal forts were opened during this period, giving access to most of the peninsula.〔 On Pico do Facho, starting in this period and extending to the 20th century, was a house and semaphore signalling post along with several military structures,〔 including excavations in the ground (channels and rectangular depressions) representing complex installations associated with these activities. In the 19th century, the area around the Fort of São Diogo was improved and remodelled in order to support the construction of military batteries, during the Liberal Wars.〔 At the beginning of the Second World War, structures were constructed on the summit of Monte Brasil to support coastal defences of the Azores, during a time when open warfare existed between the Allies and Axis.〔 Buildings to garrison troops and munitions, including several artillery and anti-aircraft emplacements were established to protect the city from assumed submarine/naval attacks on Pico das Cruzinhas and Pico do Facho.〔 In order safeguard the dynamic ecosystem of the region, the regional government established the Nature Park of Terceira (on 20 April 2011), that included the classification of Monte Brasil for the protection of the marine environment.〔Diário da República (20 April 2011), p.2355〕 The () Área Marinha Protegida de Gestão de Recursos do Monte Brasil (''Protected Marine Resource Management Area of Monte Brasil'') was established to protect the biodiversity of the fauna and marine habitats that included areas of submerse and semi-submersed grottos that exist along the cliffs.〔Diário da República (20 April 2011), p.2365〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Monte Brasil」の詳細全文を読む スポンサード リンク
