While commencement ceremonies for 90 seniors at Bishop McGann-Mercy Diocesan High School in Riverhead on June 6 were an occasion for celebration, they also formally marked the end of an era. Earlier in the day, McGann-Mercy dismissed its student body for the final time, less than three months after the Diocese of Rockville Centre announced that the East End school would close at the conclusion of the academic year because of declining enrollment and other factors.

A commencement Mass preceded the graduation, with Father Steve Maddaloni, school chaplain, serving as the main celebrant and homilist.

Bishop John Barres addressed the Class of 2018 during the graduation ceremony and later presented diplomas to its members.

The graduation, which drew a capacity crowd to the auditorium, was the final event at a school founded by the Sisters of Mercy under the title of Mercy High School in 1956.

Here is a gallery of images from the evening.
