The existing city-state architectural relics are mainly public buildings such as temples, theaters and arenas, among which temples are an important activity center of a city-state and can best represent the architectural style of that period. The life of the ancient Greeks was controlled by religion, so naturally, the largest and most beautiful building in ancient Greece was the Greek temple. The ancient Greeks believed that God was also a human being, but God was more perfect than ordinary people. They think that the place where God lives is just a more advanced house than ordinary people. Therefore, the earliest temple buildings in Greece were just rectangular buildings with porches where nobles lived. Later, the column type was added, which gradually developed from the early "end colonnade" to the "front porch", that is, the porch in front of the temple was composed of four columns, and then developed to the "front and back porch". By the 6th century BC, the portico style had evolved into the standard form of Greek temple architecture-"enclosed column", that is, the rectangular temple was surrounded by colonnades. The overall style of Greek temple architecture is solemn and elegant, with harmonious, grand and lofty beauty. These style features are obvious in all aspects.
The democratic system of the ancient Greek city-state, that is, Athenian democracy, had some drawbacks. First, only adult male Athenian freemen have citizenship, and women and non-freemen are excluded from civil politics and democratic politics. The so-called civil rights are only the privilege of adult male Athenian freemen, and the so-called democratic politics only exists within a certain range. Second, foreign slaves ruled the allies, brutally plundered the countries that joined the alliance through military violence, and pursued hegemonic policies. Third, the so-called "taking turns to govern" makes all public offices be elected by lottery, which does not guarantee that people with both ability and political integrity are firmly in power. On the contrary, it is very likely that democracy will eventually decline and die out.
