Interiors won the awards ahead of the company's final performance
Scotland's touring theatre companies have scooped six of the 10 prizes at the prestigious Critics' Awards for Theatre in Scotland (Cats).
The companies awarded were Inverness-based Dogstar, Vanishing Point and Vox Motus from Glasgow and Rowan Tree, which works from the Scottish Borders.
International co-production Interiors won three awards including best director, production and ensemble.
The organisers said Scottish theatre continued to be in "strong health".
Cats co-convenor Joyce McMillan said: "In a year when no fewer than six of the awards were won by touring companies based across the length and breadth of the country it is clear that Scottish theatre is as strong and diverse as ever, and capable of delivering unexpected thrills, from the smallest village hall to the grandest international stage.
"The high calibre of the new work produced here over the last 12 months has been inspiring, and it is especially gratifying to note that the quality of Scottish creativity is now being recognised across the world through an increasing number of international collaborations including this year's Best Production, Interiors."
Interiors is a co-production between Vanishing Point, the Traverse Theatre in Edinburgh, Napoli Teatro Festival Italia and Mercadante Teatro Stabile di Napoli, in association with Lyric Hammersmith and Glasgow's Tron Theatre.
Inspired by Maurice Materlinck's symbolist masterpiece, Matthew Lenton's production was conceived during workshops at the 2008 Naples Theatre Festival.
The final version of the piece was created with a mixed company of British and Italian actors.
The three awards came as the company prepared to give the final performance of the production at the 2009 Naples Theatre Festival.
