Rathfarnham Castle in Dublin will be officially reopened later this afternoon, a year after a "treasure trove" of 17th Century artefacts was uncovered during renovation works.
More than 18,000 different items were discovered during works to provide a new lift and staircase in the castle's southwest tower.
The items included lead-crystal drinking glasses, glass figurines, monogrammed wine bottles, coins, porcelain from China, cutlery, seeds and pips from exotic fruits, fish and bird bones, items of costume, bobbins for lacemaking, jars which may contain cosmetics and a folding toothbrush.
The horde is believed to relate to a specific household, that of Lord Adam Loftus, Viscount Lisburne, a descendant of the original Adam Loftus and a favourite of both Charles II and William of Orange at various times.

All the finds are currently distributed for analysis among numerous specialists in Ireland and the UK.
It is hoped the OPW, in conjunction with the National Museum of Ireland, will eventually mount an exhibition at the castle of some of the archaeological finds.
Some of the original structural features uncovered during the excavations have been left exposed and are now visible to visitors.
The castle, which is now fully accessible, reopens with an exhibition of works by Belfast artist Brian Ballard.
The decision to reopen the castle was welcomed by Simon Harris, Minister of State with special responsibility for the OPW.
Mr Harris said that to mark the occasion, entry into the castle will be free for the next ten days.
