Orchomenus was an ancient city of Arcadia, Greece. Originating as a prehistoric settlement, Orchomenus became one of the powerful cities in West Arcadia along with Tegea and Mantineia. The heyday of the city was between 7th–6th century BC and it became a rich city which minted its own currency.
Many monuments were revealed during the excavations and can be admired today including the theatre, the remains of the ancient agora, the city walls and the temple of Artemis Mesopolitis. Other monuments identified during the excavations are a Bouleuterion, a prehistoric tomb and a bridge of the Archaic Period.
The most important monument is the theatre (4th–3rd BC) with a capacity of 4,000. At an altitude of 800 metres it offered a spectacular view during cultural events.
Approaching the town from the south one can see tumuli on the left, chiefly composed of collections of stones as described by Pausanias. Below the acropolis is the tomb of Aristocrates and beyond are the fountains called Teneiae which Pausanias mentions (writing in the 2nd c. AD) as one of the most remarkable objects in the place. A little further are the Hellenistic ruins of Amilus.
On the southern plain is an ancient canal which conducts the waters from the surrounding mountains through the ravine into the lower northern plain.
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.
