Petroglyphs, or carved rock designs, and pictographs, or painted rock designs, are known by the general term rock art. In what are now the states of Utah, Arizona, New Mexico, Texas, and Colorado, prehistoric hunter-gatherer Indians began to decorate canyon walls, rock shelters, and boulders with rock art several thousand years ago. Navajos, Apaches, Pueblo Indians, and even Spanish soldiers and settlers continued to create rock art over the centuries.
The three major southwestern Indian horticultural groups who created rock art were the Hohokam of southern Arizona, the Mogollon of southern Arizona and New Mexico and West Texas, and the Anasazi--now known as the Pueblo Indians--of southern Utah, Northern New Mexico and Arizona. They existed from approximately A.D. 1 to A.D. 1500. In addition, the Fremont culture of Utah employed a dramatic rock-art style based on Anasazi motifs from A.D. 700 to A.D. 1200.
Since Paris is such a compact city (roughly 6 miles across), much of it can be covered on foot — especially the primary sightseeing spots in the city's center. There will be times, however, when a métro or bus ride is welcome. Some of the métro stations are worth a visit. For example, the stop for the Louvre (line 1) gives one the impression that the train has pulled into the Museum itself: the immaculate marble walls are lined with exhibits and replicas of art works, with glass cases containing various sculptures. On line 13, Varenne offers exhibits from the nearby Rodin Museum (including a replica of The Thinker), while Liège is paneled with beautiful tiles. Abbesses (line 12) features murals alongside its spiral staircase leading to one of the more elaborate of Art Nouveau entrances.
While World War I nose art was usually embellished or extravagant squadron insignia, true nose art appeared during World War II, which is considered by many observers to be the golden age of the genre, with both Axis and Allied pilots taking part. At the height of the war, nose-artists were in very high demand in the USAAF and were paid quite well for their services while AAF commanders tolerated nose art in an effort to boost aircrew morale. The U.S. Navy, by contrast, prohibited nose art, while nose art was uncommon in the RAF or RCAF.
Stonehenge is a prehistoric monument located in the English county of Wiltshire, about 3.2 kilometres (2.0 mi) west of Amesbury and 13 kilometres (8.1 mi) north of Salisbury. One of the most famous sites in the world, Stonehenge is composed of earthworks surrounding a circular setting of large standing stones and sits at the centre of the densest complex of Neolithic and Bronze Age monuments in England, including several hundred burial mounds. Archaeologists had believed that the iconic stone monument was erected around 2500 BC, as described in the chronology below. However one recent theory has suggested that the first stones were not erected until 2400-2200 BC, whilst another suggests that bluestones may have been erected at the site as early as 3000 BC (see phase 1 below). The surrounding circular earth bank and ditch, which constitute the earliest phase of the monument, have been dated to about 3100 BC.
The London Tower Bridge is often mistakenly referred to as London Bridge, which is actually the next bridge upstream. A popular urban legend is that in 1968, Robert McCulloch, the purchaser of the old London Bridge that was later shipped to Lake Havasu City, Arizona, believed that he was in fact buying Tower Bridge. This was denied by McCulloch himself and has been debunked by Ivan Luckin, the seller of the bridge. Tower Bridge is a combined bascule and suspension bridge in London, England, over the River Thames. It is close to the Tower of London, which gives it its nameName. It has become an iconic symbol of London. Tower Bridge is one of several London bridges owned and maintained by the City Bridge Trust, a charitable trust overseen by the City of London Corporation. The bridge consists of two towers which are tied together at the upper level by means of two horizontal walkways which are designed to withstand the horizontal forces exerted by the suspended sections of the bridge to the left and the right. The vertical component of the forces in the suspended sections and the vertical reactions of the two walkways are carried by the two robust towers. The bascule pivots and operating machinery are housed in the base of each tower. Its present colour dates from 1977 when it was painted red, white and blue for the Queen`s Silver Jubilee. Originally it was painted a chocolate brown colour.
