Drottningskär Citadel stands as a testament to Sweden's historical might, with construction predominantly occurring in the late 17th century. Revered as one of the nation's premier defence structures, this fortress remains remarkably preserved, offering a glimpse into Sweden's past as a formidable power. Crafted from enduring granite, the large castle encompasses a gun deck, powder magazine, and living quarters, all organised around four bastions named after queens Maria, Christina, Hedvig, and Ulrica. Although it hasn't played an active role in Swedish defence since 1895, Drottningskär Citadel remains a compelling destination. Accessible year-round via the car ferry to Aspö, visitors can explore this historical gem and immerse themselves in Sweden's military legacy.

With collected memories and traces of the history of mankind in Blekinge from the past 10,000 years, Blekinge Museum delves into the region's past, unravelling stories of local trades such as fishing, boat-building, and quarrying. A highlight within its exhibits is Grevagården, an impeccably preserved 18th-century residence adorned with an extensive array of vintage artefacts.
