Helsinki is adjacent to the Baltic Sea. It is a city that combines classical beauty with modern civilization. It is also a garden city that integrates urban architecture and natural scenery skillfully. Buildings in the city are mostly built of light-colored granite, known as the "white city in the north". Against the backdrop of the sea, whether the sea is blue in summer or drifting ice in winter, the port city always looks beautiful and clean, praised by the world as "the daughter of the Baltic Sea"
