The National Cipher Challenge

The Bletchley Park Prize-giving, February 2026

From the beginning the National Cipher Challenge has had a close relationship with the historic home of UK codebreaking at Bletchley Park, and after last year’s wonderful celebration we are delighted to be heading back there again this year.

The event will be held in February 2026, and all Gold and Silver medal winning teams will be invited. We are really looking forward to meeting them there!
