The September 11th Memorial at Masco is located outside of the library in the courtyard and was built by a group of students in 2002 (Mannheim). Physically, the monument is simplistic, however it has a deep meaning.

As described on the plaque, the two towers represent the World Trade Centers which were infamously attacked in 2001. However, it is the black glaze which adds nuance to the artwork; the glaze symbolizes the horror of that day. While the black symbolizes the tragedy that took place, it also shines and reflects the light to demonstrate how the attacks became a piece of the fabric which is American moral and strength.

Many people who were alive that day can remember exactly where they were when the towers were struck and can clearly remember what happened that day, who they were with and how the attacks changed the course of America in the years and decades to come.

The plaque is facing away from the memorial where it is visable for everyone in Robert's Library. The names of the students who worked to create this memorial are engraved on the plaque. Their names are: Brett Anderson, Kelly Connors, Katherine Clark, Diana Lyon, Katherine McQueen, Annie Russell, Meredith Turcotte, Courtney Carney, Julie Deschenes, Katherine Larkin, Anne Maclennan, Duane Persad, Jessica Stern and Vincent Vilardi. A very special thank you to Ms. Sandy Samaha who directed these students in her ceramics class, without her this monument would not exist (Mannheim).

Their work and dedication to this project will forever remain a permenant part of Masconomet history.
