Kardaki Temple is an Archaic Doric temple in Corfu, built around 500 BC in the ancient city of Korkyra. The temple features several architectural peculiarities that point to a Doric origin. The temple at Kardaki is unusual because it has no frieze, following perhaps architectural tendencies of Sicilian temples. It is considered to be the only Greek temple of Doric architecture that does not have a frieze. The spacing of the temple columns has been described as 'abnormally wide'. The temple also lacked both porch and adyton, and the lack of a triglyph and metope frieze may be indicative of Ionian influence. The temple at Kardaki is considered an important and to a certain degree mysterious topic on the subject of early ancient Greek architecture. Its association with the worship of Apollo or Poseidon has not been established.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
