The state capitol building is made of white Georgian marble. On top is the world's fourth largest self-supported marble dome. It houses the Rhode Island Charter of 1663 and other state treasures.

Providence is home to the First Baptist Church in America, the oldest Baptist church in the Americas, which was founded by Roger Williams in 1638. Providence is the home of the first fully automated post office in the country. The seaside city of Newport is home to many famous mansions, including The Breakers, Marble House and Belcourt Castle. It is also home to the Touro Synagogue, dedicated on 2 December 1763, considered by locals to be the first synagogue within the United States (see below for information on New York City's contestant), and still serving. The synagogue showcases the religious freedoms that were established by Roger Williams as well as impressive architecture in a mix of the classic colonial and Sephardic style. The Newport Casino is a National Historic Landmark building complex that presently houses the International Tennis Hall of Fame and features an active grass-court tennis club.
