Hummelstown Borough Hall is located at 136 South Hanover Street, Hummelstown PA 17036; phone: 717-566-2555.
Founded about 1740 by Frederick Hummel and known as Frederickstown until his death, spent its formative years making firearms; today  it is largely residential and agricultural, drawing a livelihood from the fertile valley and from neighboring Harrisburg, although it has a small dress factory.
Less than a mile outside Hummelstown is "Indian Echo Cave," a 450-foot cavern in a limestone ridge which reveals the usual formations named for objects they resemble. In one section of the cave Amos Wilson, the Pennsylvania Hermit, spent the last 19 years of his life, because he failed, by a few minutes, to save his sister Harriot, from hanging for the murder of her illegitimate baby.
Hummelstown is the birthplace of Alexander Ramsey. He served as the first Minnesota Territorial Governor, 2nd Governor of the State of Minnesota, a U. S. Senator, and Secretary of War for President Rutherford B. Hayes. Tow counties were named for him: Ramsey County Minnesota, and Ramsey County North Dakota.
