The Col. Charles A. Converse House on Washington Street in Norwich is a striking Gothic Revival villa, deigned by Henry Austin of New Haven. Built around 1870, it was first owned by Col. Converse, who was one of the founders of Hopkins and Allen, a major gun manufacturing company in Norwich. In 1907, the Converse Art Gallery, an addition to the Slater Memorial Museum donated by Col. Converse, opened to the public. The Converse Homestead property also has a barn built around the same time as the house.
What does the “a” stand for?
I would like to know the history on the stone wall that is part of the Col. A. Converse house, and why there are 6 pentagrams carved in it?
