Eketorp fortress is a completely excavated and reconstructed ancient fort, where the reconstructions have been carried out directly on the archaeological remains. The ring wall stands five metres high and six metres wide, and within it lie Iron Age stone houses and medieval timber-framed buildings, all reconstructed using traditional craftsmanship techniques and materials.

At the National Air and Space Museum, you can see historic aircraft, from Amelia Earhart’s Lockheed to World War II fighters, as well as spacecraft and moon landing exhibits. There’s also a planetarium, IMAX theatre, and flight simulators, plus workshops and demonstrations that make the science behind aviation and space exploration come alive.

Once the first free settlement in the Americas, founded by those who escaped slavery during the colonial period, the town of San Basilio de Palenque still stands today, and with it the unique culture of its inhabitants. A portion of the population still speaks palenquero, a creole tongue that emerged from a mix of several European and African languages, now used almost exclusively in San Basilio de Palenque. Music and dance occupy a place of paramount importance in residents' lives, with the Drums and Cultural Expressions Festival held annually in October. The palenque cuisine deserves a separate mention — a culinary tradition upheld by inhabitants of a small Colombian village has garnered international acclaim, with a cookbook written in the town receiving the highest prize at the Gourmand World Cookbook Awards in 2014. If your schedule happens to be too tight for a dedicated day trip (which earns our highest recommendation), try some of the tropical fruit sold by palenqueras in downtown Cartagena. The village was named Masterpiece of the Oral and Intangible Heritage of Humanity by UNESCO in 2005.
