The last time a stop by the Cambridge Historical Society’s Hooper-Lee-Nichols House might have topped to-do lists was at the new year, when folks were invited to come write down what they wanted to leave behind from 2020 so it could be shredded and recycled.

The Society is again looking back a year, but more somberly and sweetly.

Through March 26, the Society has planted an installation of butterflies on its Hooper-Lee-Nichols House lawn to mark the one-year anniversary of the Covid-19 pandemic and honor the Cantabrigians died from it. “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 Society said Tuesday.

Daytime temperatures are expected to be chilly Friday and Saturday but otherwise back in the 50s through the end of the installation, making it a good time for a stroll down Brattle Street.

You can visit the display at the Cambridge Historical Society’s Hooper-Lee-Nichols House, 159 Brattle St., West Cambridge. Information is here.
