Over a century old, the Speicherstadt is the world's largest integrated complex of warehouses. Visitors to Hamburg will discover a picturesque setting of Wilhelmine era Gothic architecture rendered in red brick, featuring unusual gables and towers. Precious commodities are stored at controlled temperatures behind the massive walls: coffee, tea, cocoa, spices, tobacco, and the world's largest collection of Oriental rugs. If you're pressed for time or wish to give your feet a rest after exploring the city, consider taking a one-hour evening boat tour. The Speicherstadt looks particularly enchanting at sunset.

If a trip to the theatre isn't something you would initially consider doing during your stay in Cluj, think again - the city's National Theater is heralded as one of the best in the country, and regularly puts on an ever-changing selection of musical and theatrical performances (check their website for news and schedules).

Encircled within a courtyard of modern dwelling buildings, Rotunda of St George is the oldest preserved structure in the city, which has also been declared a UNESCO World Heritage site. The beautiful cupola holds a fourteenth-century portrait of Christ surrounded by four angels.
