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 solid blocks of granite that form a five-way stone vault. Each block supports the other to create a central, covered space for reflection.
