Who We Are
We are an amateur musical theatre company with a passion and drive to put on amazing shows for the local community, providing a variety of opportunities to involve our diverse community in local theatre, on and off stage.
Colchester Operatic Society (Charity no. 1198865) was founded in 1924 and we are one of the region’s oldest musical theatre companies performing annually to rave reviews. Over the years we have put on over 130 shows/concerts involving over 8,600 cast and crew.
We currently produce a main show in the early part of the year, running for two weeks at The Mercury Theatre and a summer concert, which has been performed at a variety of smaller venues, in and around Colchester.
