Aida the Musical Nov. 17-19

The Trinity High School Fine and Performing Arts Department is proud to present AIDA by Elton John and Tim Rice. The performances will be Friday, Saturday and Sunday, November 17-19 in the Trinity auditorium.

Friday, November 17th ~ 7PM

Saturday, November 18th ~ 7PM

Sunday, November 19th ~2PM

Adapted from the four-time Tony Award-winning hit, Elton John and Tim Rice’s Aida School Edition is an epic tale of love, loyalty, and betrayal, chronicling the love triangle between Aida, a Nubian princess stolen from her country, Amneris, an Egyptian princess, and Radames, the soldier that they both love. There are action-packed scenes as well as incredible music.  The show also features a runway dancing fashion show. 

AIDA is more than just a love story.  Amneris and Aida are both powerful female future rulers who learn to transcend the vast cultural differences between their warring nations, heralding a time of unprecedented peace and prosperity.

Trinity High School will be honored with the unveiling of an honorary street sign on the 7500 block of West Lathrop on Wednesday, November 1, 2017, following our Founder’s Day mass and celebration. At 11:45am, the entire Trinity community will gather at the corner of Lathrop and Division where River Forest officials will unveil “Trinity Way.”

It is an incredible honor to mark the indelible bond between Trinity High School and the River Forest community. Beginning in the fall of 2017 Trinity opened its centennial celebration. Since 1908, the Trinity mission is focused on the education and empowerment of women. This is a core idea at Trinity passed down from the five pioneering sisters who established Trinity (then called Rosary House) to educate and empower women at a time when they did not even have the right to vote. 

It is Trinity’s role to help shape the next generations of young women – to help nurture their faith, fill their thirst for knowledge and cultivate their passion for truth and justice to make the world a better place. For 100 years, our young women have gone on to become compassionate global citizens, and we view this street sign as a powerful symbol of that legacy.

All are welcome to attend. For further information on our Centennial Celebration and all of the corresponding events, please visit

Join us for Trinity’s Centennial Celebration

Sunday, November 5th, 2017
at 10:30AM
Trinity High School’s Auditorium
Join us for Trinity’s Centennial Mass Celebrated by Reverend Monsignor Kenneth Velo. Immediately following the mass we will host an Open House reception with self-guided tours of the school. Seating is limited.  Tickets are required. 


Trinity High School has been educating and empowering young women since 1918. As we prepare for this milestone Centennial year, we are marking the beginning of our school year by observing the solar eclipse on Monday, August 21, 2017. Over 550 people gathered outside sharing this experience as a community. Coincidentally, the last solar eclipse took place 100 years ago!

Father Samuel Mazzucheli, the brave pioneer who along with a group of courageous and forward thinking Sinsinawa Dominican Sisters laid the foundation of what would become Trinity High School a century ago. It has been detailed in our archives that Fr. Mazzuchelli purchased a telescope in 1852 that would make its way to Trinity. As we gather this week to observe this historical event, we will be envisioning the initial 15 Trinity girls who shared a similar experience 100 years ago. What a beautiful way to mark the historic and unforgettable time ahead!
