Archaeologists in Kinross have uncovered a range of finds thought to be part of a medieval settlement.
The discovery was made on the site of the new Kinross High School, opposite Lethangie Farm.
The two fields forming the development site have been recognised as being of archaeological interest.
A Scheduled Ancient Monument - a site designated as being of archaeological importance - has been identified in the south field.
Excavation work, which began in March, was carried out by archaeological consultants SUAT Ltd as part of planning consent conditions imposed by Perth and Kinross Council before work on the new school begins.
Finds in the north field include a large pit with domestic rubbish in the form of small pieces of medieval pottery shards, bone and oyster shell.
A large pit with burnt stone was found, as well as a large circular enclosure ditch containing small broken pieces of medieval pottery and many rodent burrows.
Many of the deposits have been sampled for further analysis and charcoal has been recovered for dating.
Buried archaeology at the Scheduled Ancient Monument in the south field is considered to represent the remains of a prehistoric settlement which is at least 2,000 years old.
A spokesperson for the council said: "During the planning application process, the development site was recognised as being of archaeological interest by archaeologists from Perth and Kinross Heritage Trust.
"The scheduled area will be protected and will be encompassed within the new school grounds."
