The Museum of Modern Greek Art (MGA) is a major cultural institution spread across three buildings in the city's Northern part, showcasing the creative genius of 20th-century Greek artists. You'll encounter a rich array of paintings, sculptures, and drawings from luminaries like Maleas, Bouzianis, Kontoglou, Theofilos, Vassiliou, and Hadzikyriakos-Gikas. Each building offers a unique glimpse into the world of modern Greek art, making it a must-see for any art aficionado.

This one-of-a-kind nature reserve is filled with deciduous forest, seaweed belts, pines and a bloomy open ground that borders a waterfilled quarry. It also showcases the rugged beauty of Karlshamn's granite and coastal gneiss. Rich in history, the land areas harbour ancient and cultural monuments, including a Stone Age settlement, graves, and stone burials from the Bronze and Iron Ages. Notably, remnants of the Per Albin Line, a 500 km long defensive line from the Second World War, add historical significance to the reserve. Submerged in the water area around Sternö and Boön, several shipwrecks contribute to the reserve's maritime allure.

Ernest Hemingway donated his former home of two decades to "the people of Cuba" after moving away, and it remains largely undisturbed since the 1960s. Although one cannot technically come into the house, there are plenty of spots to peek in through the windows, as well as explore the premises containing a tiny cemetery of Hemingway's pet dogs and his fabled boat Pilar, docked in what once was a tennis court.
