This monument commemorates the early pioneers responsible for the development of machines that led to, or indeed were, the first electronic digital computers.


This spot was chosen because the COLOSSUS, the first effective, operational, automatic, electronic, digital computer, was constructed by the Post Office Research Station at Dollis Hill (now BT research), whose research and development later moved from that site to Martlesham, just east of here and the landowners thought this would be a suitable setting to commemorate this achievement.


The story of these machines has nothing to do with the names and companies that we associate with computers today. Indeed the originators of the computer are largely unknown, and their achievement little recorded.


All the more worth recording is that this first machine accomplished a task perhaps as important as that entrusted to any computer since.


The electronic digital computer is one of the greatest legacies the 20th century leaves to the 21st.


The History of Computing…

The shape of the monument is designed to reflect a fundamental concept in mathematics. This is explained in the frame entitled “The Monument”.


You will notice that some of the Stations are blue and some are orange. Blue stations talk about concepts and ideas pertinent to the development of the computer, and orange ones talk about actual machines and the events surrounding them.


The monument was designed and funded by a grant making charity.
