RUSI - Royal United Services Institute 123 Pall Mall, London SW1Y 5EA

Welcome to the Royal United Services Institute (RUSI), one of the oldest and most prestigious institutions of its kind in the world. Located at 123 Pall Mall in the heart of London, RUSI is a point of interest for anyone interested in military and security issues, and an establishment with a long and distinguished history.

RUSI was founded in 1831 as the Royal United Services Institution for Defence Studies, and has been at the forefront of research and discussion on military and security matters ever since. Our aim is to promote the study and understanding of defence and security issues, and to foster debate and discussion on the most pressing issues facing the world today.

At RUSI, we are proud of our long history and our reputation for excellence. Our members include some of the most distinguished figures in the fields of defence and security, and our research and analysis is widely respected by policymakers, the media and the public alike. We offer a range of events, publications and other resources to the public, designed to promote informed discussion and understanding of the key issues affecting global security.

As well as being a hub for research and discussion on military and security issues, RUSI is also a beautiful and historic building in its own right. Our headquarters at 123 Pall Mall is a Grade II listed building, originally built in the 1820s for the United Service Club. It was later acquired by RUSI in the 1940s, and has been refurbished and updated to provide a modern and comfortable environment for our members and visitors.

Whether you are a student, a policymaker, a journalist or simply someone with an interest in defence and security issues, RUSI is a must-visit destination in London. We welcome visitors from all over the world, and we look forward to seeing you soon.
