The grant will be used to conserve the priory's stonework
A 17th Century burgh hall and the ruins of a 12th Century priory are to receive a share of a £1m award from the Heritage Lottery Fund (HLF).
Linlithgow Burgh Halls, in the grounds of Linlithgow Palace, has been given a £772,500 grant.
It is to transform the original 17th Century building and 19th Century rear-wing into an arts centre and cafe.
The Tweed Forum has also been given £237,500 to conserve the ruins of Coldingham Priory.
The ruins date from the 12th Century, although it traces its descent back to one of the oldest monastic foundations in Scotland.
'Sense of place'
The HLF has said that the ruins are in a very poor state, badly eroded, overgrown and at risk of collapse.
The grant will be used for conservation, footpaths, historical interpretation and the establishment of a garden.
The stonework at Linlithgow Burgh Halls has also deteriorated and this, combined with poor access and inadequate facilities, has led to it being left unoccupied and underused.
Commenting on the announcements, Colin McLean, head of the Heritage Lottery Fund in Scotland, said: "I'm always heartened when new uses can be found for Scotland's historic buildings.
"They give a community a sense of place, of history and of identity that cannot be replaced, yet without care and attention, they would eventually be lost."
Luke Cumins, of the Tweed Forum which is co-ordinating the Coldingham project, said the investment was essential.
"The most important bit is consolidating the ruins," he said.
"The other side, which is the community element, is transforming a bit of waste ground adjacent to the priory into a community garden.
"This will be based on a monastic garden with medicinal herbs and plants and this is going to be used by the local community and the local school."
