BBC review on the Egg:

the egg is a new theatre for children, young people and families in Bath. BBC Somerset reviewer Kirsty Gardener went along to the theatre, prior to its public opening, to have a look round.

Put simply, there is nothing like the egg in Bath.

It is a child’s delight. Designed by children for children, it will host shows by children and for children, in a packed year-round programme. 

The seats are long, soft and couch-like and not for the long-legged, since they are built to child specifications.

The auditorium is cosy, seats more than 100 people and is on two levels. It’s modern but not garish, with lots of bright red drapery and red corrugated plastic walls.

Most innovative of all, it has a soundproof room where parents can take noisy children, but still watch a performance without disturbing anyone.
