This beautiful example of Spanish colonial architecture contains a small museum dedicated to the Spanish Inquisition's brutal persecution of heretics once carried out in these very chambers. Visitors can still see some of the torture devices used to extract confessions of heresy and witchcraft, along with some of the questions used in "witch" interrogations, which are still displayed on the museum wall. Needless to say, no prisoner could hope to be acquitted of their purported crimes against the Catholic Church, and most met their tragic end at the very guillotine still on display in the courtyard.

The tower, a long-standing symbol of Vilnius, is located on the 48-metre-high hill. It is named after the city’s founder, Gediminas, the Grand Duke of Lithuania. This is the only remaining part of the Upper Castle, which stood here from the 10th until the late 14th century. There is an observation deck on the top of the tower, a great place to appreciate a magnificent panorama. Gediminas Tower can be reached by foot or a funicular.

The impressive swimming centre at De Tongelreep is a great place to spend a day for the whole family. There are classes for toddlers and the elderly, as well as snorkelling lessons, water polo, and many other activities.

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.
