When Charles Carroll of Carrollton lived in the mansion here, people knocked on his door to meet the last living signer of the Declaration of Independence. After he died in 1832, in a room on the second floor, this stately home became the German Working Man's Club, and then a tenement filled with Russian-born tailors, and finally a recreation center with a basketball court. Slowly, the home is being restored but Carroll's bedroom and his library are open for visitors. The Phoenix Shot Tower nearby is open only by appointment for a 10:30am tour on Saturday or Sunday. Call 2 weeks in advance. Inside the 1828 tower, shot was made by dropping lead down the shaft.
