Hartford, Connecticut, is a small city, but it’s home to a massive American landmark: The Mark Twain House and Museum. This house was built in 1873 and designed by Edward Tuckerman Potter, a famous New York architect. Mark Twain (whose real name is Samuel Langhorne Clemens) and his wife, Olivia Langdon Clemens, lived in the house from 1874 to 1891.
