The fort at Cramond was located on the River Almond at the point where it flows into the Forth. In Roman times, there was probably a natural harbour here. One suggested interpretation is that Cramond formed a chain of Lothian forts along with Carriden and Inveresk. The fort was established around 140 during the building of the Antonine Wall, and remained in use until around 170 when the Romans retreated south to Hadrian's Wall. When the Roman Emperor Septimius Severus began the last major Roman incursion into Scotland from 205 to 214, the fort was reoccupied and enlarged. Throughout these periods of occupation a civilian settlement seems to have existed outside the fort, and some native occupation of the fort seems to have taken place after the time of Severus into the 4th/5th century and during the early Sub-Roman period. Several Roman inscriptions have been found around Crammond.
The ground plan of part of the fort is laid out in an area of open parkland. Here one can see headquarters building, granaries, workshop, together with other buildings, restored in outline. Information panels at the site link the findings of the last 50 years of excavations and recreate life in the former Roman headquarters and bathhouse.
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.
