Stockholm Archipelago is a group of around 30,000 islands, islets, and rocks along the eastern coast of Sweden in the Baltic Sea, near the city of Stockholm. The islands are mainly made of Precambrian bedrock, shaped by glacial erosion and covered in places by post-glacial sediments. The archipelago features rocky shores, forested islands, narrow channels, and sheltered bays, making it a classic example of a glacially influenced coastal landscape. - AsNotedIn
