The Semi-Circle Basel

Building community through performance

The Semi-Circle Basel is modern amateur theatrical community for actors, directors, stage managers, crew and more!

We believe that being involved in the performing arts builds community – especially important in an increasingly disconnected world.

Announcing SC Fundraising Goal & Purpose

The Semi-Circle Basel successfully weathered the past 2 years and is looking ahead with optimism and excitement to our 2022 production season.  We have three major productions planned:

  • She Kills Monsters by Qui Nguyen in June,

  • Vanya and Sonia and Masha and Spike by Christopher Durang in August, and

  • a series of short plays in November.

Click through to the “What’s On" page for dates and ticket information.  And see the Cast Announcements below to check out which actors will delight you this summer.

Meanwhile, in order to benefit the experience of both the audience and the actors at our new location, Fachwerk in Allschwil, we are excited to launch a fundraising campaign and have set a goal of CHF 5’000. This will go directly towards a new lighting and sound board as well refurbishing the Green Room and the Dressing Rooms.

We value your generosity very much in this endeavor.  If you would like to contribute directly via bank transfer, please note the following account details:

However, due to the continuously high number of infections, we recommend wearing a mask indoors when attending a Semi-Circle event.


Cast announcement

We are delighted to announce the cast for our exciting August production of
Vanya and Sonia and Masha and Spike, directed by Scott Holland, with assistant director support from Canan Adams.



Vanya: Kenner Estes
Sonia: Magda Bednarska
Masha: Eleanor Low
Spike: Adrian Oettli
Nina: Elif Arikan
Cassandra: Vasiliki Mourgela 

Winner of the 2013 Tony Award for Best Play.

This laugh out loud comedy is about adult siblings Vanya and Sonia who share a home in Pennsylvania, where they bicker and complain about the circumstances of their lives. When their movie-star sister, Masha, swoops in with her new boy toy, Spike, old resentments flare up, eventually leading to threats to sell the house. Also on the scene are sassy maid Cassandra, who can predict the future, and a lovely young aspiring actress named Nina, whose prettiness somewhat worries the imperious Masha.

At: Fachwerk, Baslerstrasse 48, 4123 Allschwil


Performance dates are:

19, 20 August & 26, 27 August 2022 all at 19:30

Tickets available - via the What's On page!
