Puente de San Martín bridge was constructed in the late 14th century by archbishop Pedro Tenorio to provide access to the old town from the west, complementing the older Puente de Alcántara linking to the east. Both sides of the bridge were heavily fortified with towers, the more recent dating from the 16th century.
The Puente de San Martín features five arches, with the largest in the middle reaching an impressive span length of 40 m. Only very few bridges in the world had reached that mark until then.
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.
