The Park Inn Hotel and City National Bank opened in 1910 and were listed on the National Register of Historic Places in 1972. The hotel is the only remaining Frank Lloyd Wright-designed hotel in the world and the bank is one of two Wright-designed banks still standing. The hotel and bank were rehabilitated in 2011.
