The Newport Colony House was designed after an English Town Hall designed by Richard Munday; Munday also designed the Seventh Day Baptist Meeting House in Newport. An open marketplace is found on the first floor of the Colony House, with civic offices on the second. The design was intended to make what is now Washington Square into an elegant meeting place. The Colony House is the fourth oldest American state house that is still standing. The mayor of Newport announced the Declaration of Independence on its front steps. Tours by appointment. Donations accepted.
