Our fascinating exhibition uses interactive displays to tell the story of how Marconi, Crompton and Hoffmann put Chelmsford on the world map as the birthplace of three key modern technologies:

• electrical engineering
• telecommunications
• precision bearing manufacture

Bright Sparks lets you discover the surprising story of Chelmsford's key industries through the firms' products, employees' own stories and hands-on science exhibits.

Top thing to see in this gallery:

• RMS Titanic's Radio Room: a reconstruction of the Radio Room on board the ill-fated Titanic

In this exhibition, you can find out more about how Chelmsford was home to the birth of live entertainment broadcasts.
