OOE's "Old" Town Hall was built in 1895 at the NE corner of Main and Hawthorne and currently serves as a community centre. Over the years, it has worn many hats.
"It has been a baby clinic, dance hall, school, kindergarten, Carnegie Library, head office of a water company, Baptist Mission, election headquarters, police commission, recreation department, home of a theatre group and a jail.
