The twinning between Rastatt and New Britain in the U.S. has existed since 1984. The cornerstone of this twinning was a stamp with the likeness of Carl Schurz, discovered by Peter Kilduff of Central Connecticut State University in New Britain. Carl Schurz was a leading revolutionary in the 1848 freedom movements. After his arrest, he managed to escape from Rastatt to the United States. There he was Minister of the Interior from 1877 to 1881.
New Britain, with a population of around 70,000, is located in the state of Connecticut on the U.S. East Coast, halfway from New York to Boston. Connecticut is known for its rich oak population as well as its productive agricultural land. Particularly worth seeing is the Indian Summer, which begins at the end of September.
