Hundreds have turned out at St Michael's Church in Creeslough for the funeral of Hugh Kelly.
The farmer and construction worker from the parish was the oldest of the victims, at just 59 years of age.
Mr Kelly will be laid to rest exactly one week on from the explosion that claimed the lives of ten people.
A jewellery box Hugh made for his niece was brought to the altar.
Parish Priest Fr. John Joe Duffy told mourners it represents his talent for craft.
“Among the symbols that will be brought forward is a jewellery box that you made,” he said.
“Representing usability to turn his hand to so many things. That attention he had for detail. That sharp eye and the many things he fixed and made for family and for friends – as Hugh would tell you himself, nobody could do it like himself.
Hughie was a farmer, who also worked in construction, and was described as 'cheery' by locals.
The Donegal village has now witnessed seven funerals since the explosion, with eight people laid to rest.
President Michael D Higgins, who has been in the village since Wednesday attended the funeral.
He will also attend the last of the funerals, which is due to be held tomorrow.
The funeral for five-year-old Shauna Flanagan-Garwe and her father Robert Garwe is also due to be held at St Michael’s in Creeslough.
