History of architecture starts when first time men though to build beautifully. A building without beauty is merely a structure, not an art. Utilitarian considerations of a building, stability and strength are works of engineers. It's the work of architects to add the beauty to it. Architecture is actually an art which guides us to harmonize in a building both the beauty and utility requirements of a building. Architecture stands at top in the category of useful arts. It is concerned with not only to provide a shelter to man but also to take cares of his basic requirements e.g. place for worship, tombs, business, memorials and other structures which are needed in complex civilization. Architecture depicts about the civilization of an age or a race. Early humans are often thought of as dwelling in caves, largely because that is where we find traces of them. The flints they used, the bones they gnawed, even their own bones - these lurk for ever in a cave but get scattered or demolished elsewhere. Caves are winter shelter. On a summer's day, which of us chooses to remain inside? The response of our ancestors seems to have been the same. But living outside, with the freedom to roam widely for the purposes of hunting and gathering, suggests the need for at least a temporary shelter. And this, even at the simplest level, means the beginning of something approaching architecture. The aim of this work has been to sketch the various periods and styles of architecture with the broadest possible strokes, and to mention with such brief characterization as seemed permissible or necessary the most the leading facts of architectural history.
