Inspection work at a historic landmark took five weeks to complete.
Caerlaverock Castle has been closed to the public since the spring of 2021 due to concerns over the condition of its masonry, although the grounds can still be accessed.
However, Historic Environment Scotland has now completed its investigation and is now considering what repair work needs to be carried out.
A number of historic sites across the region have been closed for months – if not years – for similar reasons.
The organisation has revealed it can take more than a month to complete the masonry inspection, with work at Caerlaverock Castle taking 25 working days. Inspections at Carsluith Castle and Threave Castle near Castle Douglas have been completed.
The former reopened in February, with the grounds at Threave expected to reopen soon.
Plans are also being developed to reopen the grounds of Dundrennan Abbey and the shop at Cardoness Castle near Gatehouse, although the sites themselves have still to be inspected.
The shop at MacLellan’s Castle in Kirkcudbright reopened on Monday, with an inspection planned for June.
The grounds of Sweetheart Abbey in New Abbey have remained open and this weekend there will be performances from Lady Devorgilla and a monk to mark the site’s 750th anniversary.
Director of operations at HES, Craig Mearns, said: “Dumfries and Galloway is home to some of the country’s most significant heritage sites and I am delighted to announce that we are increasing access to some sites where it is safe to do so.
“We are working as quickly as we can to roll out our nationwide programme of inspections, and we appreciate the public’s patience while we undertake this necessary work.
“Our specialist team is progressing with inspections in the area, with MacLellan’s Castle, Dundrennan Abbey and Cardoness Castle due to be inspected in the coming months.
“The inspection results for Caerlaverock Castle and Carsluith Castle will now be analysed to inform any interventions or repairs that will be required in order to provide additional visitor access to the historic sites, and I would ask visitors to check our website for the latest information.”
