Slane Castle in Co Meath is to reopen to the public tomorrow, nearly 10 years after it was partially destroyed by fire.
Castle owner, Lord Mount Charles, believes the reconstructed and restored building is "bigger and better" than it was before the November 1991 fire.
The castle was designed by James Wyatt and Francis Johnson, and built in the late 18th and early 19th century. All of the castle's internal features have been reproduced in the style of that time.
The castle was not insured and annual open-air concerts have contributed to the cost of the restoration.
Slane Castle opens from 1 to 17 August when it will close temporarily to allow for preparations for the two sell-out U2 concerts.
U2 played support to Thin Lizzy at the first concert at the castle, 20 years ago.
