Augustae was built as a fortified military camp in the mid-1st century, as the first fortification was made of wood and earth. The castle was naturally protected to the south by the Ogosta River, to the east and north by marshland. Access was possible only from the western side, where a fortified wall reinforced with a ditch was erected. In the 2nd-4th century Augustae developed as a Roman and an early Byzantine urban centre. Its total area reaches about 9 hа.
The fortress had the shape of an irregular pentagon extending from north to south. The fortress wall was dug inside up to 2.30 m and its thickness reached 2.50 m. Its walls were made of roughly worked stones, bonded with white mortar. The fortress had three gates - one to the west, north and east. The defence system consisted of protruding towers. The necropolis was located west of the fortress. Archaeologists have uncovered the fortification system of the Early Roman camp and the settlement dating to the Late Antiquity. The western wall with three rectangular towers and the western gate of the stone fortification have been explored. The site of the severely destroyed northern gate has also been established. Buildings have been uncovered in the inner part of the site, located in the approximate centre of the early Roman camp. In the 3rd–4th century the city was restored periodically after the invasions of the Goths. The last destructive invasion by the Avars in the 6th century marked the end of its existence.
References:Dryburgh Abbey on the banks of the River Tweed in the Scottish Borders was founded in 1150 in an agreement between Hugh de Morville, Constable of Scotland, and the Premonstratensian canons regular from Alnwick Abbey in Northumberland. The arrival of the canons along with their first abbot, Roger, took place in 1152.
It was burned by English troops in 1322, after which it was restored only to be again burned by Richard II in 1385, but it flourished in the fifteenth century. It was finally destroyed in 1544, briefly surviving until the Scottish Reformation, when it was given to the Earl of Mar by James VI of Scotland. It is now a designated scheduled monument and the surrounding landscape is included in the Inventory of Gardens and Designed Landscapes in Scotland.
David Erskine, 11th Earl of Buchan bought the land in 1786. Sir Walter Scott and Douglas Haig are buried in its grounds.
