A plaque has been unveiled at the world's oldest post office to celebrate 300 years of service.
Sanquhar post office in Dumfries and Galloway began as a staging post for mail carriages in 1712.
Sub-postmistress Penny Murphy said: "I feel very honoured to run such a historic post office. As well as our regular customers, we also get inquiries from people across the world asking for a hand-stamp from Sanquhar post office.
"I'm delighted with the new plaque, which proudly proclaims our place is postal history."
It is eight years older than an office in Stockholm which is the second oldest in the world, followed by one in Santiago, Chile, established in 1772.
Sanquhar is recognised as the world's oldest by both the Universal Postal Union and the Guinness Book of World Records.
The branch is a popular attraction for postal and stamp enthusiasts from across the UK and the world. They visit to have their letters marked with a hand-stamp bearing the legend: "The World's Oldest Post Office."
The plaque was presented to Ms Murphy by Sally Buchanan, the Post Office group's head of network operations for Scotland, and David Mundell, the local MP.
