Founded by David I in 1128 for Tironensian monks and dedicated to the Virgin Mary and St John, Kelso Abbey quickly became the wealthiest abbey in Scotland, controlling vast estates across the Borders. Its position close to the royal burgh of Roxburgh — then one of Scotland's most important towns — made it a place of political as well as religious significance.
What stands today is a satisfying fragment: the massive west tower with its Romanesque stonework, imposing enough to suggest the scale of what once existed. The original building was an unusual double-cruciform design with two transepts — a rare arrangement in Scotland. The abbey survived repeated English raids during the Wars of Independence but was devastated in the 1540s during Henry VIII's Rough Wooing, when English forces burned it twice in quick succession. It never recovered, and the Reformation finished what the soldiers had started. Entry is free. The site is quiet even in summer — fewer visitors come here than to the more elaborate ruins at Melrose or Jedburgh, which is itself a reason to stop.
