Today is the anniversary of a rather ignominious date in Boston. An anti-Irish, anti-Catholic, anti-immigrant mob vented their rage by burning down and Ursuline convent that stood on Ploughed Hill in Charlestown. Today the hill’s been torn down and the site of the convent is now within the boundaries of Somerville near the site of the East Somerville branch of the public library. One of the things that fascinates me about this story is that the ruins of the convent remained on the hill for decades after its destruction as if to reproach those who burned it. For more about the burning of the Charlestown convent I recommend reading Fire and Roses by Nancy Lusignan Schultz, an excellent history of this event.
