The former home of a playwright on the edge of Welwyn Hatfield will host a celebration on Saturday, marking 100 years since character Eliza Doolittle was introduced to the world.

Actors will be at Shaw’s Corner, in Ayot St Lawrence, to perform sections of George Bernard Shaw’s Pygmalion – later adapted for the musical My Fair Lady.

Visitors to the National Trust site have been urged to come in costume, with prizes on offer for the best dressed.

“We’re really looking forward to celebrating Eliza’s 100th birthday here at Shaw’s Corner,” said assistant house steward Lizzie Dunford.

“The property hosts outdoor performances of Shaw’s plays every summer, but this is a unique and rare chance for us, and our visitors to get more fully involved with Pygmalion, Eliza and Henry Higgins.”

When the play opened to the London public on April 11, 1914, it was an instant success.

The event will run from noon to 5.30pm, with performances at 12.10pm and 1.45pm.
