Tiryns is a Mycenaean archaeological site in Argolis in the Peloponnese, and the location from which the mythical hero Heracles was said to have performed his Twelve Labours.
Tiryns was a hill fort with occupation ranging back seven thousand years, from before the beginning of the Bronze Age. It reached its height of importance between 1400 and 1200 BC, when it became one of the most important centers of the Mycenaean world, and in particular in Argolis. Its most notable features were its palace, its Cyclopean tunnels and especially its walls, which gave the city its Homeric epithet of 'mighty walled Tiryns'. Tiryns became associated with the myths surrounding Heracles, as the city was the residence of the hero during his labors, and some sources cite it as his birthplace.
The famous megaron of the palace of Tiryns has a large reception hall, the main room of which had a throne placed against the right wall and a central hearth bordered by four Minoan-style wooden columns that served as supports for the roof. Two of the three walls of the megaron were incorporated into an archaic temple of Hera. The site went into decline at the end of the Mycenaean period, and was completely deserted by the time Pausanias visited in the 2nd century AD.
In 1300 BC the citadel and lower town had a population of 10,000 people covering 20–25 hectares. Despite the destruction of the palace in 1200 BC, the city population continued to increase and by 1150 BC it had a population of 15,000 people.
Along with the nearby ruins of Mycenae, UNESCO designated Tiryns as a World Heritage Site in 1999 because of its outstanding architecture and testimony to the development of Ancient Greek civilization.
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.
