The 75-year-old Cambridge Matignon School said it will close at the end of the current academic year on June 8. The Catholic institution in North Cambridge made the “somber announcement” Tuesday on its website.

Financial challenges were cited as the cause of the closing in the letter signed by Marc-Anthony Hourihan, president of the school’s board of trustees and an alum from 1989.

“Members of our school leadership group have exhausted all options to continue forward,” Hourihan said. “We have not been able to secure the funds necessary to support the long-term sustainability of the school. That, combined with the challenge of ongoing demographic shifts among middle and high-school-aged children, has resulted in insurmountable financial pressures that forced us to make this decision.”

The school would work to ensure a respectful transition process with support for everyone affected, Hourihan said.

Decreases in attendance and schools are cited. The Archdiocese of Boston gave Matignon’s enrollment at just 300 this academic year – a figure that was expected to fall, though students come from as far as Woburn and Stoneham. The closing is part of a wave affecting Catholic institutions; there have been similar media reports in recent months from schools in Brighton, Newton and Fall River, which follow news from recent years of the Archdiocese making other properties available for sale.

The 95,532-square-foot property at 1 Matignon Road was assessed this year at a value of $32.3 million, according to city records. It holds three main buildings, including the three-story brick high school.

Matignon was founded in 1945 by then Archbishop of Boston Richard J. Cardinal Cushing, according to a school history, and “entrusted to the Congregation of the Sisters of Saint Joseph … and still to this day has a member of the order on staff.”

In addition to academics, the school was known for a hockey program that won 10 state championships from the mid-1970s through the 1980s and was selected as the best high school hockey team in the nation five times, according to the school history. National Hockey League players including Tom O’Regan, Stephen Leach, Shawn McEachern and Niko Dimitrakos began at Matignon under coach Marty Pierce, who retired in 2004 with a 650-166-61 record that produced 19 NHL draft picks.
