Some of the most scenic vistas in Vietnam can be admired from a bird’s eye view aboard a plane that takes off from the capital city of Hanoi. Flying over the green landscape of northeastern Vietnam, this aeroplane tour is possibly the best way of seeing the limestone karst formations of Ha Long Bay.

Built in the 13th century and dedicated to the Assumption of Mary, the Basilica di Santa Maria Gloriosa dei Frari, usually called the Frari, is the largest church in Venice and an important example of Venetian Gothic ecclesiastical architecture. It holds many masterpieces of Venetian art from the Renaissance period, which is simply a delight for the eye. Titian, the most renowned member of the Venetian school of painting of the 16th century, not only has paintings here, Assumption of the Virgin (1516–18) and Pesaro Madonna (1519–26), as this is also his final resting place.
