Roger Williams National Memorial is a landscaped urban park located on a common lot of the original settlement of Providence, Rhode Island by Roger Williams in 1636. Bounded by North Main, Canal, Smith, and Haymarket Streets, the memorial commemorates the life of the co-founder of the Colony of Rhode Island and Providence Plantations and a champion of the ideal of religious freedom. Williams, banished from Massachusetts for his beliefs, founded this colony as a refuge where all could come to worship as their conscience dictated without interference from the state. This park is the 20th smallest national park in the nation.
