Given the question: Information:  - The Alpine Rhine Valley is a glacial alpine valley, formed by the part of the Alpine Rhine (German: ) between the confluence of the Anterior Rhine and Posterior Rhine at Reichenau and the Alpine Rhine's mouth at Lake Constance. From Reichenau, the Alpine Rhine flows east, passing Chur and turning north, forms the border between the canton of St. Gallen of Switzerland on the left, west side and first Liechtenstein and then Vorarlberg, Austria on the right, east side. The Swiss-Austrian border follows the historical bed of the Rhine, but today the river follows an artificial canal within Austria for the final . The Rhine Valley in this area extends to about . Its upper third has the character of an Alpine valley, enclosing a bottom plain of about across. Downstream of Vaduz, the valley widens considerably, developing into a broad plain, measuring some across at its lower end along the southern shores of Lake Constance. From the point of the Rhine's emergence from Lake Constance, it is known as High Rhine.  - The Alps are the highest and most extensive mountain range system that lies entirely in Europe, stretching approximately across eight Alpine countries: Austria, France, Germany, Italy, Liechtenstein, Monaco, Slovenia, and Switzerland. The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the FrenchItalian border, and at is the highest mountain in the Alps. The Alpine region area contains about a hundred peaks higher than 4000 metres (just over 13,000 feet).  - Italy, officially the Italian Republic, is a unitary parliamentary republic in Europe. Located in the heart of the Mediterranean Sea, Italy shares open land borders with France, Switzerland, Austria, Slovenia, San Marino and Vatican City. Italy covers an area of and has a largely temperate seasonal climate and Mediterranean climate; due to its shape, it is often referred to in Italy as "lo Stivale" (the Boot). With 61 million inhabitants, it is the fourth most populous EU member state.  - France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories. The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, and from the Rhine to the Atlantic Ocean. Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans and had a total population of almost 67 million people as of January 2017. It is a unitary semi-presidential republic with the capital in Paris, the country's largest city and main cultural and commercial centre. Other major urban centres include Marseille, Lyon, Lille, Nice, Toulouse and Bordeaux.  - A principality (or princedom) can either be a monarchical feudatory or a sovereign state, ruled or reigned over by a monarch with the title of prince or by a monarch with another title within the generic use of the term "prince". Terminology. Most of these states have historically been a polity, but in some occasions were rather territories in respect of which a princely title is held. The prince's estate and wealth may be located mainly or wholly outside the geographical confines of the principality.  - The Swiss Plateau or Central Plateau  constitutes one of the three major landscapes in Switzerland alongside the Jura Mountains and the Swiss Alps. It covers about 30% of the Swiss surface. It comprises the regions between the Jura and the Alps, partly flat but mostly hilly, and lies at an average height between 400 and 700 m AMSL. It is by far the most densely populated region of Switzerland, and the most important with respect to economy and transportation.  - The Rätikon is a mountain range of the Central Eastern Alps located at the border between Vorarlberg, Liechtenstein and Graubünden. It is the geological border between the Eastern and Western Alps and stretches from the Montafon as far as the Rhine. In the south, the Prättigau is its limit, in the north the Walgau. In the east, it borders the Silvretta groups.  - Vorarlberg is the westernmost federal state ("Bundesland") of Austria. Although it has the second-smallest area (Vienna is the smallest) and population (Burgenland is less populated), it has the second-highest population density (after Vienna). It borders three countries: Germany (Bavaria and Baden-Württemberg via Lake Constance), Switzerland (Graubünden and St. Gallen) and Liechtenstein. The only Austrian state that shares a border with Vorarlberg is Tyrol to the east.  - Liechtenstein , officially the Principality of Liechtenstein, is a doubly landlocked German-speaking microstate in Central Europe. It is a constitutional monarchy with the rank of principality, headed by the Prince of Liechtenstein.  - A federal republic is a federation of states with a republican form of government.

A mountain system or system of mountain ranges, sometimes is used to combine several geological features that are geographically (regionally) related. On Earth, most significant mountain ranges are the result of plate tectonics, though mountain ranges are formed by a range of processes, are found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets.  - Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries.  - A constitutional monarchy (also known as a parliamentary monarchy) is a form of monarchy in which the sovereign exercises their authorities in accordance with a written or unwritten constitution. Constitutional monarchy differs from absolute monarchy (in which a monarch holds absolute power), in that constitutional monarchs are bound to exercise their powers and authorities within the limits prescribed within an established legal framework. Constitutional monarchies range from countries such as Morocco, where the constitution grants substantial discretionary powers to the sovereign, to countries such as Sweden or Denmark where the monarch retains very few formal authorities.  - The Prättigau Valley, in the canton of Graubünden (Grisons), Switzerland, is home to the world-famous ski resorts of Klosters and neighbouring Davos in the Landwasser Valley.  At its heart is the river Landquart. The valley extends upwards from Landquart, a key transport terminal just north of Chur, the capital of Grisons. It is a popular tourist destination for winter and summer activities, including downhill and cross country skiing, tobogganing and hiking. Traditionally, towns in the Prättigau were reliant on the lumber industry, although the income from tourism has largely replaced that.  - The Rhine (, , ) is a European river that begins in the Swiss canton of Graubünden in the southeastern Swiss Alps, forms part of the  Swiss-Austrian, Swiss-Liechtenstein, Swiss-German and then the Franco-German border, then flows through the Rhineland and eventually empties into the North Sea in the Netherlands.  The largest city on the river Rhine is Cologne, Germany, with a population of more than 1,050,000 people. It is the second-longest river in Central and Western Europe (after the Danube), at about , with an average discharge of about .  - The Central Eastern Alps, also referred to as Austrian Central Alps or just Central Alps comprise the main chain of the Eastern Alps in Austria and the adjacent regions of Switzerland, Liechtenstein, Italy and Slovenia.  - Mittlerspitz is a mountain on the border of Liechtenstein and Switzerland in the Rätikon range of the Eastern Alps east of the town of Balzers , with a height of 1,897 metres ( 6,224 ft ) .  - Lake Como ("Lago di Como" or locally in Italian, also known as Lario , after the Latin name of the lake; "Lagh de Comm" in Lombard; Latin: Larius Lacus) is a lake of glacial origin in Lombardy, Italy. It has an area of 146 square kilometres (56 sq mi), making it the third-largest lake in Italy, after Lake Garda and Lake Maggiore. At over 400 metres (1,300 feet) deep, it is one of the deepest lakes in Europe, and the bottom of the lake is more than 200 metres (660 ft) below sea level.  - Central Europe lies between Eastern Europe and Western Europe. The concept of Central Europe is based on a common historical, social and cultural identity. Central Europe is going through a phase of "strategic awakening", with initiatives such as the CEI, Centrope or V4. While the region's economy shows high disparities with regard to income, all Central European countries are listed by the Human Development Index as very highly developed.  - Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe. It includes 16 constituent states, covers an area of , and has a largely temperate seasonal climate. With about 82 million inhabitants, Germany is the most populous member state of the European Union. After the United States, it is the second most popular immigration destination in the world. Germany's capital and largest metropolis is Berlin. Other major cities include Hamburg, Munich, Cologne, Frankfurt, Stuttgart and Düsseldorf.  - The name Western Alps refers to the western part of the Alpine range. The term has different meanings according to the classification of the Alps in use. The peaks and mountain passes are higher compared to the Eastern Alps, while the range itself is not so broad and more arched.  - The Splügen Pass (German: "Splügenpass"; Italian: "Passo dello Spluga"; el. 2,115 m) is a high mountain pass which marks the boundary between the Lepontine and Rhaetian Alps, respectively part of the Western and Eastern Alps.  - Balzers is a town and community located in southern Liechtenstein.

It extends from the city of Bludenz and the Verwall Alps in the north, to the Silvretta and Rätikon mountain range in the south. Piz Buin is with 3312m the highest peak within the Silvretta mountain range.  - Eastern Alps is the name given to the eastern half of the Alps, usually defined as the area east of a line from Lake Constance and the Alpine Rhine valley up to the Splügen Pass at the Alpine divide and down the Liro River to Lake Como in the south. The peaks and mountain passes are lower compared to the Western Alps, while the range itself is broader and less arched.  - The city of Bern or Berne (; Bernese German: "Bärn" ) is the de facto capital of Switzerland, referred to by the Swiss as their (e.g. in German) "Bundesstadt," or "federal city". With a population of 141,762 (November 2016), Bern is the fourth most populous city in Switzerland. The Bern agglomeration, which includes 36 municipalities, had a population of 406,900 in 2014. The metropolitan area had a population of 660,000 in 2000. Bern is also the capital of the canton of Bern, the second most populous of Switzerland's cantons.  - Geneva (, , , ) is the second most populous city in Switzerland (after Zürich) and is the most populous city of Romandy, the French-speaking part of Switzerland. Situated where the Rhône exits Lake Geneva, it is the capital of the Republic and Canton of Geneva.  - Switzerland, officially the Swiss Confederation, is a federal republic in Europe. It consists of 26 cantons, and the city of Bern is the seat of the federal authorities.  The country is situated in Western-Central Europe, and is bordered by Italy to the south, France to the west, Germany to the north, and Austria and Liechtenstein to the east. Switzerland is a landlocked country geographically divided between the Alps, the Swiss Plateau and the Jura, spanning an area of . While the Alps occupy the greater part of the territory, the Swiss population of approximately eight million people is concentrated mostly on the plateau, where the largest cities are to be found: among them are the two global cities and economic centres Zürich and Geneva.  - A landlocked state or landlocked country is a sovereign state entirely enclosed by land, or whose only coastlines lie on closed seas. There are currently 48 such countries, including four partially recognised states. Only two, Bolivia and Paraguay in South America, lie outside Afro-Eurasia (the Old World).
