Frederick Castle is one of the most important buildings in Copenhagen. When you think of Frederick, you know that it refers to the German Emperor Frederick. It is also a deep historical relationship with this castle. The castle has mountains, waters and woods. It is winter when I go. I parked outside the castle. There is an automatic toll machine. I saw the first reaction of the time written above was the English "time". Later, I learned that it means "hour" in Danish. After paying in advance (Nordic high trust in people's honesty, Therefore, there is no stop bar for parking billing, consciously pay the parking fee according to the number of hours of parking planned), follow the path through the tall city gate to enter the castle, see that there are still people under construction here, it is said that the Nordic countries are very well-being, people work short hours, and the wages are high. Social security is all available, it is really a sense of communism, so the Chinese here can have several children, can only be supported by working as a tour guide, but can not help thinking that if the Chinese migrant workers who are really working overtime rush in, The Nordics who had been well-reared had long been robbed of their jobs. There was a big lake in the castle, with swimming swans on it, and the towering trees and green lawns around it were really refreshing. Continue forward there are statues of many Nordic mythological figures, and the trees often see the birds docking, which is really a harmony between man and nature. The interior of the castle is an exhibition hall. Several exhibition halls describe the history of the monarchs of the Danish dynasty. They have their living room and library, some stoves for burning fires, and realistically reflect the scene at that time. There are many oil paintings and cultural relics in the room, as well as some soldiers' armor and sculptures. Out of awe and protective attitude, there was not too much photo and touch. Like European castles, Frederick Castle is a treasure of historical culture and architectural art, but especially the beautiful natural scenery and ecological atmosphere, which makes it different from ordinary castles, if you go to Denmark to play, it is still very much to see.
