The border between the modern states of Switzerland and Italy extends to 744 km,〔(National boundary ) (swisstopo)〕 from the French-Swiss-Italian tripoint at Mont Dolent in the west to the Austrian-Swiss-Italian tripoint near Piz Lad in the east. Much of the border runs across the High Alps, rising above 4,600 meters as it passes east of Dufourspitze, but it also descends to the lowest point in Switzerland as it passes Lago Maggiore below 200 meters. The border is a product of the Napoleonic period, established with the provisional constitution of the Helvetic Republic of 15 January 1798, restored in 1815. While this border existed as a border of Switzerland from 1815, there was only a unified Italian state to allow the existence of a "Swiss-Italian border" with the formation of the Kingdom of Italy in 1861, it previously comprised the borders between Switzerland and the Kingdom of Sardinia, the Kingdom of Lombardy–Venetia and the province of Cisleithania of Austria-Hungary. There remained some territorial disputes after the formation of the Kingodom of Italy, resolved in the ''Convenzione tra l'Italia e la Svizzera per l'accertamento della frontiera fra la Lombardia ed il Cantone dei Grigioni'' of 1863.〔(original text at admin.ch )〕 Other Swiss-Italian treaties regarding the course of the border date to 1873/4,〔BS 11 83, SR 0.132.454.1〕 1936/7〔SR 0.132.454.1 / AS 1969 1308〕 and 1941.〔0.132.454.2, ''Abkommen zwischen der Schweizerischen Eidgenossenschaft und dem Königreich Italien über die Festlegung der italienisch-schweizerischen Grenze auf der Strecke zwischen Run Do oder Cima Garibaldi und Mont Dolent'', 24 July 1941〕 Since 1946, it has remained unchanged as the border between the Italian Republic and the Swiss Confederacy, with the exception of minor corrections and exchanges of territory, such as the inclusion of the Lago di Lei barrage in Switzerland in the 1950s.〔treaty of 1952, ratified 1953 (Switzerland) and 1955 (Italy), entered into effect in 1955. (【引用サイトリンク】url=http://www.admin.ch/opc/it/classified-compilation/19520241/196306260000/0.132.454.21.pdf )〕 The border separates the Swiss canton of Valais from the Italian Aosta Valley and Piedmont region, the canton of Ticino from Piedmont and Lombardy, and the canton of Grisons from Lombardy and South Tyrol. Running east from Mont Dolent, the border touches Grand Golliat and the Great St Bernard Pass and then visits a series of three-thousander peaks including Mont Velan, Mont Brulé and Tête Blanche before rising to 4171 m at Dent d'Herens and to 4,476 m at Matterhorn, followed by Furgghorn, Breithorn, Zwillinge, Monte Rosa at 4554 m, and Grenzgipfel just east of Dufourspitze at 4618 m. The border now encircles the Italian Domodossola valley, passing Gonda, Monte Leone, Bortelhorn, Helsenhorn, traversed by the Simplon Tunnel connecting Brig with Varzo, Grieshorn just south of Nufenen Pass, and forming the western border of Ticino runs across Marchhorn, Basodino, Pizzo Fiorera, Wandfluhhorn, Pizzo Quadro, Pizzo di Porcaresc, Pilone and descends below 1000 m running across Centovalli along a stretch of the Melezza. It rises again to Pilone peak before descending to Lago Maggiore between Brissago and Cannobio, on the left bank making landfall at Caviano and passing west of Lugano and the villages of ''Malcantone'' to Ponte Tresa at Lake Lugano. It then forms the southernmost corner of Switzeland including Chiasso, turning north again outside of Como and now forming the eastern border of Ticino running west of Lake Como, of passing Lake Lugano again west of Lugano and touching Monte Boglia, Cima di Fojorina, Gazzirola, Cima di Cugn, Pizzo Campanile, again reaching 3000 m at Pizzo Quadro between Val Mesolcina and Chiavenna, and further north to Pizzo Tambo, Splügen Pass and Piz Timun. The Swiss-Italia border here has the peculiarity of including the reservoir of Lago di Lei in Italy but in an artificial salient including the reservoir's dam in Switzerland. Turning south again it traverses Val Bregaglia at Castasegna and turns east towards Cima di Castello, now forming the northern border of the Valtellina, a territory that was lost by the Three Leagues in 1797 with the formation of the Cisalpine Republic. Val Poschiavo remains part of Grisons, and is separated from Valtellina by the border passing just north of Tirano, turning north again along Piz Paradisin, Munt Cotschen, Piz da l'Acqua to the inclusion of Livigno in Italy. The border now follows the southern watershed of Val Müstair, touching Piz Murtaröl, Piz Tea Fondada, Piz Schumbraida, Piz Umbrail until it reaches the pass road connecting Vinschgau with the Valtellina and Stilfserjoch. The border now turns north for a final stretch separating Val Müstair and the Engadin from Vinschgau, South Tyrol, terminating at the Austrian-Swiss-Italian tripoint just north of Piz Lad. ==References== 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「Swiss–Italian border」の詳細全文を読む スポンサード リンク
