March 2021 marks the one-year anniversary of the COVID-19 pandemic. To honor the Cantabrigians who have died, we are installing markers on the lawn of our headquarters, the Hooper-Lee-Nichols House. Each marker, a butterfly, a symbol of hope and the shape of Cambridge itself, represents a life lost to the virus and a missing piece in the mosaic of stories that together make up the history of Cambridge. The installation will be up through March 26.
