Mysionis was a large ancient town and fortress. It is located 7 km away of town of Targovishte in region Krumovo Kale, on the northern edge of the steep gorge of the river Vrana in Preslav Mountains.
The site dates back to 6th-7th centuries. After excavations there were found remains of fortress walls 3-4 meters in height, remains of a large church, guard and residential buildings. The slopes of the hills were occupied of neighborhoods and in one of them was found a second large Christian church.
In the vicinity were found also marble columns, antique stone objects, Roman pottery, medieval cemeteries and others. Probably Mysionis existed until the end of the 14th century and was destroyed during the Ottoman invasion.
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.
