The Space
Built in 1904 for $5,000, the Old Town Hall in Winchester has gone through many changes. From 1906 to 1961, it was the village library. During the 1920’s, it showcased movies, plays, and concerts with local dances held upstairs. For 65 years, the Old Town Hall acted as Winchester’s local jail, and visitors can still see evidence of jail cells in the form of bars on windows and original cell doors. From 1970 to 1980, the Ontario Provincial Police made their headquarters there.
True to it's history of versatility, the Old Town Hall is now a beautiful, intimate theatre with seating for 97 guests. Since 1996, it has been the home of the local Dundas County Players theatrical society, "A Night at the Movies" movie viewings, concerts, dinner theatre, comedy shows, and many other forms of live entertainment.
Now, we are bringing more life to the theatre, hoping to showcase this beautiful space that Winchester is lucky to be able to call it's own.
