Greeks took great care in designing their buildings, especially the temples, rows of tall columns surrounded them, they were very carefuly when they measurede these columns, because columns sanding in a long row, often looked as though they curved in the middle, and to prevent this optical illysion, they made their columns bulge slightly in the middle.
They wanted their buildings to reflect the greatness of their cities. The most impressive of all was the Parthenon in Athena, and was built on the Athenian acropolis; the interior was decorated with carvings and columns.
