The Temple of Artemis is an Archaic Greek temple in Corfu, Greece, built in around 580 BC in the ancient city of Korkyra. The temple was dedicated to Artemis. It is known as the first Doric temple exclusively built with stone. It is also considered the first building to have incorporated all of the elements of the Doric architectural style. Very few Greek temple reliefs from the Archaic period have survived, and the large fragments of the group from the pediment are the earliest significant survivals.
The temple was a peripteral–styled building with a pseudodipteral configuration. Its perimeter was rectangular, with width of 23.46 m and length 49 m with an eastward orientation so that light could enter the interior of the temple at sunrise. It was one of the largest temples of its time.
The metope of the temple was probably decorated, since remnants of reliefs featuring Achilles and Memnon were found in the ancient ruins. The temple has been described as a milestone of Ancient Greek architecture and one of 150 masterpieces of Western architecture. The architecture of the Corfu temple may have influenced the design of an archaic sanctuary found at Sant'Omobono in Rome which dates to the archaic period and incorporates similar design elements.
The massive altar of the sanctuary is precisely rectangular and stood in front of the temple. It was 2.7 m. wide and 25 m. long. Only 8 m. of its northern section survive. The rest of the altar was built over, under the foundations of the Saint Theodore monastery.
Kaiser Wilhelm II, while vacationing at his summer palace of Achilleion in Corfu and while Europe was preparing for war, was involved in excavations at the site of the ancient temple.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
