Hannas Church was likely built during the latter part of the 12th century and possesses a well-preserved medieval character. The original church was a typical Romanesque structure with a semi-circular apse, choir, and nave. In the 15th century, the church was vaulted, and a robust stair-gable tower in the west, along with a porch in the north, were added.
The benches feature old folk paintings and are marked with farm numbers. The church's oldest item is the richly sculpted baptismal font by Sighraf. The font is as old as the church itself, adorned with biblical figures on the base and scenes from the Bible on the basin.
The altarpiece dates back to 1651. Additionally, there is a triumph crucifix from around the year 1300 in the church.
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.
