Sites around the world, with a pic and a brief discription of each - ancient cities to natural wonders:
Ruins of the Buddhist Vihara at Paharpur
Brief Description
Evidence of the rise of Mahayana Buddhism in Bengal from the 7th century onwards, Somapura Mahavira, or the Great Monastery, was a renowned intellectual centre until the 12th century. Its layout perfectly adapted to its religious function, this monastery-city represents a unique artistic achievement. With its simple, harmonious lines and its profusion of carved decoration, it influenced Buddhist architecture as far away as Cambodia.
Medieval City of Rhodes

With the Palace of the Grand Masters, the Great Hospital and the Street of the Knights, the Upper Town is one of the most beautiful urban ensembles of the Gothic period.
