Post Office Research Station, Research station in Dollis Hill, United Kingdom
The Post Office Research Station spans multiple buildings across a complex where scientists conducted telecommunications and computing research during the 20th century.
The facility opened in 1933 under Prime Minister Ramsay MacDonald and became the birthplace of Colossus, the first programmable electronic computer in 1943.
Teams of engineers and mathematicians at the station developed innovations that transformed British telecommunications, including the speaking clock and ERNIE for Premium Bonds.
The main building has been converted into residential apartments named Chartwell Court, while the surrounding area contains affordable housing units.
A secret two-level underground bunker called Paddock was constructed beneath the station in 1939 as an alternative Cabinet War Room.
