Tourbet el Bey stands as the most significant royal mausoleum in Tunisia. The monument serves as the final resting place for the Husainid dynasty rulers who governed from 1705 to 1957. Its distinctive green fish-scale domes crown an imposing quadrangular structure, blending Ottoman grandeur with Italianate stucco work and Andalusian tile motifs. Built during Ali Pasha II’s reign (1758–82), the interior reveals a spatial homage to Istanbul’s Hagia Sophia, where vaulted ceilings display intricate polychrome stucco arabesques. The tombs tell silent stories: male rulers are marked by marble carvings of their headgear (turbans or chechia caps), with tassel counts denoting rank, while women’s graves bear simple plaques. A courtyard paved with memorial slabs connects the chambers, their walls shimmering with historic ceramic tiles.

An astonishing 2,000-year-old temple, now a church, the Pantheon is a remarkable building to visit when in Rome. Built as a temple to all gods, the Pantheon is the best-preserved marvel from ancient Rome. Its main and most fascinating feature is the design of the dome and open oculus, the only source of natural light. Tourists from around the world flock here to see what Michelangelo defined as an "angelic and not human design". The Pantheon also houses the tomb of the great painter Raphael. The square in front of the Pantheon is called Piazza della Rotonda. It is located near Piazza Navona and Campo de Fiori, so take the opportunity to stroll around in this area; there is much to see.
