Sean Collier Memorial

J. Meejin Yoon

Location

Vasser St. Entrance to the Ray and Maria Stata Center

Situated on MIT’s campus in honor of Officer Sean Collier who was shot and killed on April 18th 2013, the Collier Memorial marks the site of tragedy with a timeless structure—translating the phrase “Collier Strong” into a space of remembrance through a form that embodies the concept of strength through unity. The memorial is composed of thirty-two blocks of granite that form a five-way stone vault. Each block supports the other to create a covered space for reflection. The Collier Memorial evokes a star shape as well as an open hand, referencing MIT’s motto, Mens et Manus (Mind and Hand). The ovoid space at the center of the radial walls creates a passage, a marker, and an aperture that reframes the site.

The design combines age-old structural techniques for spanning masonry vaults with new digital fabrication and structural computation technologies to create an unprecedented form. The structure relies on the exact fit of thirty-two stone blocks to transfer loads in pure compression from stone to stone. The shallowness of the massive vault overhead creates an effect of suspension and weightlessness, while the tapered geometry of the individual stone blocks that form the compression ring reveals the keystone geometry of the masonry arch.

This didactic visualization of forces is consistent with MIT’s ethos of openness and transparency, while the idea that all five walls are needed to achieve a stable form is symbolic of a community coalescing to commemorate a loss. The Memorial offers the opportunity to remember Officer Sean Collier and honor his life, service, and represent shared values: openness in the face of threat, unity through diversity, and strength through community.

Strength Through Unity: The making of the Collier Memorial at MIT

MIT appreciates thoughtful offerings left in the memory of and honoring Officer Sean Collier. Please note that in the interest of public safety and the appearance of the memorial, MIT will remove the items placed at the site of the memorial. Thank you for your understanding.
