This was just added to the list by UNESCO - Situated in north-eastern Wales, the 18 kilometre long Pontcysyllte Canal is a feat of civil engineering of the Industrial Revolution, completed in the early years of the 19th century.

The use of both cast and wrought iron in the aqueduct enabled the construction of arches that were light and d strong, producing an overall effect that is both monumental and elegant.

Picture of a waterfall of the Iguazu falls seen from the Brazilian side on May 7, 2009. An acute drought in Brazil has hit the famed horseshoe-shaped Igauzu falls which straddle two countries, cutting back the tumbling waters to reveal the rocky sides. Only a third of the usual volume of water is now flowing over the top of the stunning falls, which were listed as a world heritage site by UNESCO in 1984 and border both Brazil and Argentina, Globo television said.

A Tibetan pilgrim spins prayer wheels as she offers prayers while encircling the grounds of the Potala Palace in Lhasa, 26 August 2003.
