Blue Hill Meteorological Observatory, located at the top of a scenic mountain range south of Boston, is a unique American institution. Founded in 1885 by Abbott Lawrence Rotch as a private scientific center for the study and measurement of the atmosphere, it was the site of many pioneering weather experiments and discoveries. The earliest kite soundings of the atmosphere in North America in the 1890s and the development of the radiosonde in the 1930s occurred at this historic site.
As First Lady to the 2nd President of the United States and mother of the 6th President, Abigail Adams is one of the most respected and influential women of the early revolutionary period of American history. Built in 1685, the Abigail Adams Birthplace was home to this exceptional woman for the first twenty years of her life until she married John Adams in 1764. It has survived two relocations and restoration work was recently completed. The birthplace is maintained by the Abigail Adams Historical Society and open for tours the second Sunday of the month from May to November.
