Architecture has evolved over different eras, starting with basic materials like wood and animal skins, then progressing to stone, brick and steel. Early civilizations like Egypt and Greece made important contributions - Egyptian architecture featured grand monuments and pyramids made possible using granite, sandstone and limestone, while Greek architecture emphasized beauty and order with styles like Doric, Ionic and Corinthian columns. Later, Romans advanced engineering with roads, aqueducts and bridges, and medieval architecture included Romanesque and Gothic styles before the Renaissance looked to classical Roman designs.
