The school, opened by the Presentation Sisters in 1901, was known as Presentation Convent Primary School, usually abbreviated to 'The Convent'.
The open school event provided the perfect opportunity for past pupils, former staff members and friends of the school to rekindle many memories.
A spokesperson for the school described it as “a truly special morning”.
"We were delighted to listen to so many stories and memories from their time in school.
"We started off the morning with a beautiful mass in St Patrick’s chapel followed by an open school to welcome members of the community.
"Thank you to everyone who came out to celebrate our 125-year celebration and to everyone who made today happen.”
