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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
