Police Scotland officers in the Borders are appealing for witnesses following damage to an external wall at Melrose Abbey.
A 10m stretch of the dry stone wall on Annay Road, Melrose is thought to have been hit by a vehicle on March 17.
It is thought the repair will cost more than £1,000.
"The dyke, which has been reconstructed within the past 18 months, appears to have been hit at low speed, possibly by a large vehicle carrying out a three-point turn.
"There are no markings or debris left on the road so it looks like the wall has been hit with low impact. But it is a hit and run nevertheless, and a costly one, so we would urge any members of the public with any details that may assist the investigation to come forward."
Around 10 thousand were in Melrose on Saturday the 12th of April for one of the biggest events on the sporting calendar. Visitors arrived from across the world to watch and take part in the Melrose Sevens.
The annual event is worth thousands to the Borders economy and sees some of the World's top sevens stars go head to head. Jenny Longden reports.
