Built when Naples was under Spanish rule, Palazzo Reale is one of the four royal residences around Naples used by the Bourbon Kings during their reign over the Kingdom of the Two Sicilies. Today, the grand palace and its sprawling grounds are home to the Teatro di San Carlo, the Teatrino di Corte, the National Library, and a captivating museum that offers a glimpse into 17th to 19th-century history through the exquisitely decorated royal apartments. The Royal Gardens, an enchanting sanctuary within, boast tree-lined avenues adorned with rare plants, statues, and hidden gardens, adding to the historical allure of this magnificent landmark.

Qasr Al Hosn, the oldest and most significant building in Abu Dhabi, was built around the 1790s as the city's first permanent structure, initially serving as a watchtower to oversee coastal trade routes and protect the growing settlement. Over the centuries, it has been the home of the ruling family, the seat of government, a consultative council, and a national archive. Today, it stands as a living memorial and narrator of Abu Dhabi's history. The main entrance is adorned with colourful Islamic-style tiles, and inside, centuries-old mashrabiya screens and carved wooden doors showcase the enduring architectural beauty.

This is one of the most important archaeological museums in the world: it contains bronzes, sculptures and many other objects from the Bourbon collection, as well as from the historical sites of Pompeii and Ercolano.
