Stonehenge
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 The surrounding circular earth bank and ditch, which constitute the earliest phase of the monument, have been dated to about 3100 BC. The site and its surroundings were added to the UNESCO' World Heritage sites 
Protest Groups - A protest expresses a strong reaction of events or situations. The term protest usually now implies a reaction against something, while previously it could also mean a reaction for something. Protesters may organize a protest as a group as a way of publicly and forcefully making their opinions heard in an attempt to influence public opinion or government policy, or may undertake direct action in an attempt to directly enact desired changes themselves.
Self-expression can, in theory, in practice or in appearance, be restricted by governmental policy, economic circumstances, religious orthodoxy, social structures, or media monopoly. When such restrictions occur, opposition may spill over into other areas such as culture, the streets or emigration.
A protest can itself sometimes be the subject of a counter-protest. In such a case, counter-protesters demonstrate their support for the person, policy, action, etc. that is the subject of the original protest.
Prehistoric is a term used to describe the period before recorded history. Paul Tournal originally coined the term Pré-historique in describing the finds he had made in the caves of southern France. It came into use in France in the 1830s to describe the time before writing, and the word "prehistoric" was introduced into English by Daniel Wilson in 1851.
The term "prehistory" can be used to refer to all time since the beginning of the universe, although it is more often used in referring to the period of time since life appeared on Earth, or even more specifically to the time since human-like beings appeared. In dividing up human prehistory, prehistorians typically use the Three age system, whereas scholars of pre-human time periods typically use the well defined Rock record and its internationally defined stratum base within the geologic time scale. The three-age system is the periodization of human prehistory into three consecutive time periods, the Stone, Iron and Bronze age.
