Their Majesties King Tupou VI and Queen Nanasipau’u Tuku’aho were the guests of honour at the celebrations.
Ex-scholars, current students and teachers joined invited guests on 24 May for the anniversary.
King Tupou named a new school hall ‘Fale Masiva’ in remembrance of the 50t h birthday.
In his address, he noted the orange colour of the school uniform and compared it to gold saying it was hard and unbreakable.
Guests were treated to a feast prepared by Siasi ‘o Tonga Tau’ataina and celebrations went well into the day.
Tailulu College was established on 2 February 1967 with more than 400 students.
There are currently more than 600 students studying at Tailulu College.
Prior to the establishment of the college, the church hosted a primary and school called the Ako Tonga in Nuku’alofa and the outer Islands.
