Brown University's Ladd Observatory (named for a governor) was built in 1890 on what was one of the highest points in Providence called Tin-top Hill (named for hanging tin cans in a tree for use by surveyors). Besides the telescope, they also followed transits (instruments that allowed measurements of the heavens) and furnished time signals to fire stations (much like the six beeps that signal the exact hour on BBC Radio) only stopping in the 1970's when they observed that no one was receiving them any longer. It is open to the public on Tuesday nights.
