The performance area is 8.0m wide and 5m deep with a horseshoe frontage between two areas of side seating. The extreme side seat areas shown on the diagram have now been converted into rigid platforms either side which can be used for performance – for example to accommodate musicians or a narrator.

The main stage has full black backing drapes to three sides which can be opened or closed according to requirements, and there are accessible wings to each side, as well as a large backstage area.

The main stage has recently been raised by approximately 300mm (excluding the extreme front end of the horseshoe) and this area has black ‘joelmat’ stage flooring in an area 8.0m wide by 5m deep.

Rehearsal Space

We already welcome several of Cornwall’s best known theatre and dance companies who rehearse here and use the Tolmen Centre as a space to launch new shows. Subject to availability we are happy to allow the venue to be used by all groups – amateur and professional – and our charges are kept modest to encourage this.

Phone us or email tolmen@constantinecornwall.com to find out more.


The theatre space is on the first floor and is accessed up staircases on either side of the building. There is disabled access in the form of a stairlift. Changing, toilet and shower facilities are on the ground floor. We do not have a hearing loop.


The lighting rig now includes about 25 mixed Fresnel Parcan and Profile lanterns mountable on bars A-B and C-D with some extension bars. These are all controlled from a Zero88 Jester 12/24 channel programmable desk at the rear of the auditorium, with 12 dimmer channels feeding two sets of 6 15A sockets in the centre of AB and CD. There are dimmable houselights and a series of fixed floodlights controlled separately. There are also two portable tripod lighting rigs with their own dimmers ( Zero88 Alphapacks with a total of 6 channels) to allow lights to be mounted in alternative sites and linked by DMX to the light desk (or for use downstairs if needed).


There are two active RCF 312 Mk3  PA speakers with stands, which run from a large Allen and Heath mixer. A multicore cable of 16 channels links the sound desk at the rear of the auditorium to a feed point in the lefthand wing. We have a number of stage monitors, a separate large subwoofer, and several medium grade microphones. There are two sets of inexpensive radio mics (VHF) with optional headsets (not high quality and of variable reliability). There is also a Peavey 3000 Escort portable PA with its own passive speakers which can be sited anywhere. We retain the services of a professional sound engineer for events which need specialist expertise and/or equipment.


We have a powerful NEC 5200 lumen HD projector and several screens including a large (12’x 9’) portable screen and two retractable screens fixed in the downstairs spaces. The downstairs screening area has 5:1 surround sound. This allows the screening of movies from DVD and also provides facilities for mixed media productions.
