In 1951, a group of friends gathered to read a play for pleasure. They enjoyed it so much they decided they would form a group and perform it. That fall, they met again at a tea room in downtown
Belleville to plan a public meeting in the Corby Library for forming a theatre guild in
Belleville.
The Voice of the People, a play by
Robertson Davies, was one of the first
one act plays performed. It went on to win the Eastern Ontario Drama League Festival and was invited to the
Dominion Drama Festival in
Saint John,
New Brunswick, the next spring. With the onset of
television, the theatre struggled to stay alive with little money or location to operate from. Places were used that ranged from the third storey of a downtown building, to a donated room at the back of a building, to a vacant storefront. In 1969, the city of
Belleville provided the guild with use of the D.L. Storey Building on Pinnacle Street, which was formerly a
Salvation Army Citadel. The guild members were responsible for all operating costs of the building, including utilities, heat, repairs and maintenance, plus any renovations that are required. It was then renamed the Pinnacle Playhouse and it has been the source of its success ever since. By the time the theatre celebrated its 50th anniversary in 2001, it had established itself as Belleville's primary (and at times only) hub for live theatre with early members including Jim Alexander, Liz Marshall and Steve Forrester. The latter served at BTG in a creative capacity for exactly 50 years. Today the Belleville Theatre Guild, at Pinnacle Playhouse, puts on five shows annually. Each season culminates with a musical. In addition to their regular season they are a venue for the Belleville Doc Fest, Night Kitchen Too (a musical variety performance), and occasional screenings of silent films.
Marianne Ackerman has held public readings of her in-progress works at the venue. Beginning in 2014, BTG began hosting local playwrights with an annual off-season show called the Evening of One-Acts. Playwrights whose short works have debuted here include Peter Paylor, Judie Preece, Maurice Leslie, Wayne Clark, Ian Feltham, Keith Taylor and Adri Boodoosingh. Past productions from this theatre that have won Best Production from the EODL Full-Length Festival include ''Who's Afraid of Virginia Woolf
in 1999, Talley's Folly
in 2003, and Between Breaths'' in 2024. ==Administration==
