As one of the most beautiful and appealing caves in Ha Long Bay, Sung Sot is a dazzling work of nature, astonishingly vast in size, despite its inconspicuous appearance from the outside. The rocky entrance down into the cave, coated in dense vegetation, leads to two large limestone-laden chambers, each meticulously decorated with a millennia-old ceiling of delicately formed stalactites. The impressive rock formations are colourfully lit up and can be admired from the comfort of a smooth walking path that traverses the cave.

Once the temporary retreat and later home to decorated Roman Emperor Hadrian, Villa Adriana dates back millennia when it was conceived as an 'ideal city' with baths, pools, fountains, and lush gardens. The structure combined elements of Greek, Roman, and Egyptian influences. Since 1999, Villa Adriana has been on the UNESCO list of World Heritage Sites.

Sandwiched between the Palatine and Capitoline hills, the Forum Romanum (Roman Forum) is an open-air forum that was once the commercial, political, social, and religious hub of ancient Rome. Throughout the Imperial period, Emperors like Julius Caesar and Augustus expanded the Forum to include temples, statues, monuments, a senate house, and law courts. Today, the Forum Romanum is one of the most visited archaeological sites in the world and offers fascinating insights into Roman civilisation.

Set in what used to be the country retreat for Pope Julius III, the Etruscan museum in Rome stores some impressive artefacts of the mysterious Etruscan and pre-Roman treasures. The Sarcophagus of the Spouses depicting a reclining man and woman on its lid is the masterpiece here and a true example of art from the 6th century BC.
