Porton Down - United Kingdom

[NOTE: New Site Manager to be confirmed. Andrew Sier is a temporary site contact] UK ECN site. Dstl Porton Down is located in Southern England on the Wiltshire/Hampshire border. It is owned by Defence Science and Technology Laboratory (Dstl) and is used to deliver high-impact science and technology (S&T) for the UK's defence, security and prosperity. It has been closed to the public for over 100 years, resulting in it missing out on the agricultural revolution which affected the rest of the country. This is why it constitutes the largest uninterrupted tract of semi-natural chalk grassland in Britain.
