Clarke Memorial Hall was erected by Mary Louise Clarke in 1922 as a memorial to her husband, Alfred Russel Clarke. He had died of pneumonia contracted as a result of the sinking in 1915 of the Lusitania, on which he was a passenger. The Hall was donated to the United Church and used as a Sunday School. During the Depression it was handed over to the Village of Port Credit and used as a Community Hall. It was the site of the Port Credit Municipal Offices from 1941 to 1974. Since then it has been used for meetings, auctions and various events, and as a theatre. The Hall is built in Spanish Colonial Revival style. Designated under the terms of the Ontario Heritage Act.
