HQ London District is the main headquarters for all British Army units within the M25 corridor of London. It is responsible for all Regular units, Army Reserve units and cadet attachment (ACF and CCF). It also provides for London's ceremonial events as well as supporting operational deployments overseas.
HQ London District organises the main military Ceremonial Events such as State Visits, Trooping the Colour and Beating Retreat every June at Horse Guards.
Ceremonial duties are an important part of Army history and tradition, and all soldiers undertaking this role are highly trained who also play an important part in military operations worldwide.
Ceremonial events take place throughout the country, and indeed the world, but few are as high profile as those that draw millions of tourists to London year after year.
The prestigious honour which puts them centre stage at the height of the London tourist season is in recognition of the 25th anniversary of the Corps which is being celebrated this year.
Coldstream Guards troop their colour to celebrate Her Majesty The Queen’s official birthday.
The official birthday of the Sovereign is marked each year by a military parade and march-past, known as Trooping the Colour. This takes place each June on Horse Guards Parade in London.
