The recently expanded Cowan Pottery Museum is located primarily on the first floor of Rocky River Public Library (renovated in 2006-2007). It features over 1200 pieces of
a distinctive form of American art pottery created by R. Guy Cowan and his associates at the Cowan Pottery Studio in Lakewood, Ohio from 1913-1917, and in Rocky River, Ohio from 1920-1931.

It was one of the nation’s leading potteries during the 1920s, and the Cleveland area’s only major pottery. Cowan Pottery represents a visual cultural heritage unique to Rocky River and Cleveland.
