The community of Mohill will go into lock-down tomorrow morning in preparation for the celebrity wedding of the year.
Roads around Lough Rynn Castle and Aughavas will be closed from early morning and local residents have been issued with permits by gardai.
But the concerned couple have written to residents living on the Lough Rynn estate apologising in advance for any disturbance caused by their weekend-long celebrations.
Approximately 10 of the 30 or so houses within the walls of the 300-acre estate on the shores of Lough Rynn, near Mohill, county Leitrim, are occupied full time.
But they will be under lock-down from 6am tomorrow morning when the road surrounding the estate will close and residents will only be able to leave or enter the estate with special permits being issued by gardai.
A source close to the bridal party revealed that the couple had written letters to the residents apologising to them for the disruption to their lives.
"They are really blown away by the location and love the fact that it is very intimate but they are sensitive to the fact that others are living in the vicinity," said the source.
But not everyone is happy with the arrangements.
According to local councillor Enda Stenson, residents were "a little annoyed" by the heightened controls.
