Embark on a guided exploration of Cartagena that winds through the city’s streets, showcases its great Roman Theatre, and delves into its ancient past. Cartagena’s roots date to 227 BC and you’ll venture back to those early years at the ruins of the Punic Wall. This marked the city’s first defensive rampart, built by the ancient Carthaginians to thwart off Roman siege, which would prove unsuccessful. Enjoy some free time in the heart of the city to browse the local shops before continuing the Roman Theatre of Cartagena. Marvel at this sprawling theatre excavated in 2003 that once played host to throngs of cheering Roman citizens. Continue down narrow streets dotted with modernist buildings from the 19th century. Witness the Consistorial Palace, the ornate City Council building, and the city’s main thoroughfare, Calle Mayor, on an excursion filled with epic history and stunning architecture.
