More than a year ago, three artists adorned all sides and surfaces of three different pumphouses on the Esplanade. I had meant to connect and celebrate these accomplishments at that time. Now at the start of a new year, I can do that with additional appreciation of their presence. Though pumphouses along the Charles River have always been essential in regulating water drainage, their cement block structures were neglected and defaced until funds from the Esplanade Association allowed artists to transform their appearances in 2019.
