Lost monastery masonry may have been reused for hospital's drain
Archaeologists believes they have found fragments of masonry from a medieval monastery in Perth
Surviving parts of a monastery set up by King James I of Scotland almost 470 years ago may have been found in an old drain.
The Charterhouse was established in Perth for monks of the Carthusian Order, external, and at the heart of the complex was a lavishly decorated church.
The monastery was later demolished and over the centuries the medieval site disappeared under a hospital and houses.
During an excavation last month, archaeologists and volunteers uncovered an 18th Century culvert that appeared to have been partly made using stone from the torn down monastery.

The culvert once drained waste water from King James VI Hospital, which was built around 1749-1750 and was converted into flats in the 1970s.
The drain was discovered during the dig in a grassy open space at the former hospital.
Covering the top of the drain were flat stones, which are believed to be medieval masonry.
Archaeologist Dr Gavin Lindsay told BBC Scotland News: "You can see clear chisel marks from when they had been worked very carefully to create these beautiful smooth sides.
