Visby is the capital of the Gotland island in the Baltic Sea. It is a Viking town, and hence the architecture and even the culture will speak stories of this bravest clan the world has ever seen. Apart from this, you will also find several structures delineating the medieval period wonderfully.
It's the home to several church ruins dating back to the 12th century, like St. Clemens, St. Karin, and St. Nicolai and Drottens. You can take a stroll through the famous ring wall sprawled throughout 3.5 kilometers. This is why it's one of the best places in Sweden to visit for historic and natural experiences.
