请用英语帮我介绍一个国家，比如爱尔兰，利比亚，希腊。

Switzerland is also known as "Confoederatio Helvetica", therefore the abbreviation CH. "Confoederatio" stands for "confederation", "Helvetica" derives from the Latin word "Helvetier", the name of the people who lived in the area which became later Switzerland.The capital of Switzerland is Bern City, also the capital of the canton .One of the key features of Switzerland is its cultural diversity. The ancestors of the people how live in this country today have their origins in different cultures. The most obvious result of this cultural variety is the fact, that - even if Switzerland is only a small country - there are as much as four different official languages: German (74%), French (20%), Italian (4%) and Romansh (1%) - the remaining 1% speaks other languages.
