Pyramids at Giza
Pyramids at Giza. Satellite image of the three pyramids at Giza, in northern Egypt. The pyramids are thought to have been built between 2600 and 2500 BC, as tombs and monuments for members of the ruling dynasties of ancient Egypt. The largest pyramid (lower left) was built for King Khufu, or Cheops. Its construction is thought to have taken over 20 years, and for many centuries it was the tallest building in the world. The pyramid at centre right was built for King Khafre, son of Khufu. The smallest pyramid (upper right) was built for King Menkaure. The pyramids at Giza are the only one of the Seven Wonders of the World still intact.

Easter Island statues
Easter Island statues. Row of megalithic moai statues on Easter Island (Rapa Nui) in the South Pacific. The statues top an ahu (burial platform) and look inland from beside the sea. This is Ahu Tongariki. These megaliths were carved from volcanic rock by the islanders from 400- 1500 AD. Around 1000 statues were carved, with about 100 of these re-erected by archaeologists. They are 3-12 metres tall and weigh up to 85 tonnes. Carving and erection ceased with the deforestation of the island, partly to provide rollers and levers to erect the statues. This led to soil erosion, starvation, civil war and the collapse of the island's culture.

'Fountains in Philadelphia', 1874. Creator: W. Roberts
'Fountains in Philadelphia', 1874. Horse troughts and fountains in public parks and gardens in Philadelphia, Pennsylvania, USA. 'The thirsty wayfarer, whether man or beast, will find no lack of fountains whereat to quench his thirst in Philadelphia. There are scores of these grateful drinking-places on the high- and by-ways of the city and suburbs, some of them, as may be seen by the accompanying illustration, not without a picturesque or artistic beauty and fitness in their design, which does not render the water less refreshing or the pilgrim less appreciative. These street fountains are due to the humane and enlightened labors and taste of a few gentlemen, who, in 1869, formed themselves into a Fountain Society for this beneficent object, and, either through their personal and pecuniary efforts and assistance, or by the influence of their example upon others, these well-springs of wholesome refreshment have been offered to the parched throats of hundreds of thousands of their fellow-creatures'. From "Picturesque America; or, The Land We Live In, A Delineation by Pen and Pencil of the Mountains, Rivers, Lakes...with Illustrations on Steel and Wood by Eminent American Artists" Vol. II, edited by William Cullen Bryant.
