Where was the first youth hostel opened?

In 1907, a young German schoolmaster had an idea. He decided to turn his little school house into a dormitory for the summer holidays.Anyone who brought his sleeping bag and cooking equipment along could stay there at a very small amount of money. The idea was a success. A few years later, a dormitory was set up in an old castle nearby. This was the first Youth Hostel. Today, young students and workers of every country can meet in hostels and get to know each other.When young people arrived at a hostel, they have only to show their card of membership in a hostel organization in their own country. This card will permit them to use the facilities of hostels all over the world at a minimum price. Since the end of World War II, hostels have been opened in Africa and Asia. Today, there are thousands of centers in 62 countries on five continents.These hostels have facilities for more than 250,000 young people who can travel to different parts of their own country or the world, without spending a lot of money.
