Cullerlie stone circle, also known as the Standing Stones of Echt, consists of eight irregular stones of red granite arranged at approximately equal intervals to form a circle of 10.2 m diameter, enclosing the same number of small cairns.
At the time that the circle was built in the second millennium BC, the surrounding landscape was characterised by wet bogs, and the stones were transported to the site from higher ground some distance away. The tallest of the stones marks the north side of the circle. A 2004 survey of the site discovered that several of the stones had been carved with previously unnoticed cup marks.
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.
