The Carroll Mansion is named for Charles Carroll of Carrollton, the last living and only Roman Catholic signer of the Declaration of Independence. He spent the last 12 winters of his life at the Mansion and welcomed a stream of visitors who wanted to meet тАЬthe relic of the Revolution.тА? In 1832, Carroll died in the Mansion at the age of 95. In subsequent years the house became a saloon, immigrant tenement apartments for German and then Russian Jews, and finally a sweatshop. Baltimore City purchased the Carroll Mansion in 1914 and used it for a vocational school and then a recreation center before boarding it up in 1954.
