Described as principal structure associated with the history of weather observation in the United States, this observatory is home to the oldest continuous weather record in North America. Founded in 1885 by Abbott Lawrence Rotch as a weather station and research facility, it is the place of many pioneering weather experiments and discoveries.
The observatory building was completed by the end of 1884
and the first regular observations begun on February 1, 1885. The observatory
founder, Abbott Lawrence Rotch, was only 25 years old when he constructed the
first small stone weather Observatory. The observatory remains active to this
day, and stands as a monument to the science of meteorology in the United
States. It makes weather observations such as temperature, atmospheric pressure,
sky cover, and minutes of sunshine.
