The Vasa Museum is Stockholm’s most visited attraction, built around the astonishingly preserved warship Vasa, which sank on its maiden voyage in 1628 and was salvaged largely intact in 1961. The towering, ornately carved ship fills a purpose-built hall, surrounded by exhibitions on its construction, sinking and the people aboard. A ticketed visit offers a vivid window into 17th-century Sweden and a genuinely awe-inspiring sight, making it an essential stop for anyone visiting the Swedish capital.
