Sweden is one of the largest countries in Europe, with great diversity in its nature and climate. Its distinctive yellow and blue flat is one of the national emblems that reflect centuries of history between Sweden and its Nordic neighbours.

In terms of surface area it is comparable to Spain, Thailand or the American state of California.

The national costume of Swedes is still worn on special occasions. The men's national costume consists of embroidered waistcoats, breeches and felt hats. The women's costume consists of a flared skirt, brightly coloured apron, a waistcoat and bonnets. The clothes are often embroidered with floral designs.
