Sunday talk details annexation of Dot by Boston in 1870

The Dorchester Historical Society (DHS) will host a virtual Zoom event examining the 1870 annexation of Dorchester by Boston— and its impact on development— next Sunday (April 18) from 2 p.m. to 4 p.m. 

DHS President Earl Taylor will host the illustrated presentation, which will examine how the dramatic increase in residential development in the years just before and after the 1870 annexation of the Town of Dorchester to the City of Boston was spurred in part by the desire to provide housing for the city’s burgeoning population.

Using historical images of turn of the century housing stock and other documents and source materials, Taylor will show how that period of development shaped the Dorchester we know today. 

The event is free and open to the public. To register, visit
