FOTA House is set to receive national recognition from the Irish Heritage Council.
The council is to bestow full museum status on the house under the Museum Standards Programme for Ireland at a ceremony on Monday.
The accolade recognises the high standards the house has set for itself in recent years, including the care and maintenance of its collection, the range of events it stages each year, and its conservation efforts.
Fota House has been working through the programme for the last five years and will be awarded the highest honour on the scheme having met requirements for 34 different standards.
To date, of the 57 participants to enter the programme, just 29 have achieved full accreditation. Another 11 have been awarded interim accreditation, with the remaining ones working through the programme.
Other sites with full accreditation include Donegal County Museum, the Old Library in Trinity College Dublin and the Pearse Museum in Rathfarnham.
In the eight years since Fota Gardens was acquired by the Irish Heritage Trust, it has come a long way.
It is now recognised internationally for its collection of Irish 18th-century landscape paintings, 18th and early 19th century Irish carved furniture and a unique wallpaper archive among many other objects in its own very special and historic setting.
Officials at the Trust described the museum accreditation as ‘perfectly in sync with the Trust’s values of best practice,’ adding that Fota will now be able to apply for international grants and loans of objects with confidence.
