Alfonsino Castle, also known as Red Castle, is located on the Island of St. Andrew, at the port of Brindisi. This fortification dates back to 1481 and it was completed in 1492 by Ferdinand I of Aragon. It was built in defence of the city from possible sea attacks.

The National Archaeological Museum, in Exarchia, is home to Ancient Greece’s most spectacular pieces. One room contains Schliemann’s finds from Mycenae, another has the famous frescoes from Santorini on display. There is also a fine collection of idols from the Cyclades and ceramics from all parts of the Mediterranean. The star of the museum is the Antikythera Mechanism, an ancient hand-powered orrery, described as the oldest example of an analogue computer used to predict astronomical positions and eclipses decades in advance. This scientific marvel is dated somewhere between 205 and 60 BCE.

The Cave of the Seven Sleepers in ar-Rajib village ties Islamic tradition to physical geography. According to the Quran, devout youths fleeing Roman persecution around AD 250 took refuge here, awakening 309 lunar years later in a testament to divine protection. The site, rediscovered in 1951, now includes a mosque built above the cavern, where an imam often explains the story’s theological importance. Visitors enter through the mosque (head cover required for women) to see the rock-hewn cave and adjacent Byzantine-era tombs. Unlike ornate shrines, the site’s power lies in its simplicity: the low-ceilinged grotto and quiet courtyard encourage reflection. While Jordan isn’t the only country claiming this legend (others exist in Turkey and Syria), the presence of 3rd-century Christian graves lends archaeological weight.
