Gateway Arch

The Gateway Arch is a 630-foot (192 m) monument in St. Louis, Missouri, United States. Clad in stainless steel and built in the form of a weighted catenary arch,[5] it is the world's tallest arch,[4] the tallest man-made monument in the Western Hemisphere,[6] and Missouri's tallest accessible building. Built as a monument to the westward expansion of the United States,[5] and officially dedicated to "the American people," the Arch, commonly referred to as "The Gateway to the West" is the centerpiece of Gateway Arch National Park and has become an internationally recognized symbol of St. Louis, as well as a popular tourist destination.

Parthenon

The Parthenon is a former temple on the Athenian Acropolis, Greece, dedicated to the goddess Athena, whom the people of Athens considered their patron. Construction began in 447 BC when the Athenian Empire was at the peak of its power. It was completed in 438 BC, although decoration of the building continued until 432 BC. It is the most important surviving building of Classical Greece, generally considered the zenith of the Doric order. Its decorative sculptures are considered some of the high points of Greek art. The Parthenon is regarded as an enduring symbol of ancient Greece, Athenian democracy and Western civilization and one of the world's greatest cultural monuments. To the Athenians who built it, the Parthenon, and other Periclean monuments of the Acropolis, were seen fundamentally as a celebration of Hellenic victory over the Persian invaders and as a thanksgiving to the gods for that victory.
