Abington Chancellor Damian J. Fernandez and Karen Wiley Sandler, chancellor emerita, slid the box into the base of the building, and construction workers quickly sealed it behind the cornerstone.
The box was filled with memorabilia including a photo of the first class of resident assistants. Fernandez, Sandler, the Student Government Association president, and others wrote letters they hope will be read by Abington students in 2067 when the capsule is due to be unearthed.
Faculty, staff, students, and members of the construction team signed the box before it was tucked away.
The Lions Gate will open for the fall 2017 semester, housing 402 students in apartment-style living.
