Plans are in high gear for the 150th anniversary celebrations of the Immaculate Conception High and Prep schools at Constant Spring, St. Andrew.

The series of events will kick off with a special Mass on January 13 at the Holy Trinity Cathedral, which will be celebrated by coadjutor Archbishop Donald Reece.

Following the Mass will be a brunch in the auditorium of St. George's College.

The 150th anniversary celebrations were launched in October with a ground-breaking ceremony for the high school's new sixth form block, which has received a $2 million contribution from the NCB Foundation.
