Armoury House is an 18th‑century Georgian manor, built and furnished in 1735, that now serves as the regimental home of the HAC.  It is a Grade II‑listed building with six main rooms used for events, including conferences, dinners, weddings, and other private functions.
Armoury House sits at the centre of one of the most peculiar and continuous military histories in London, stretching back over four and a half centuries.  It began not as a grand manor, but as a practical base for training London’s citizen‑soldiers, and only later became the elegant Georgian headquarters you see today.
The HAC’s history is full of odd twists. During the English Civil War, the Company effectively backed both Parliament and the Royalists at different moments, so its members fought on both sides.  In the Gordon Riots of 1780, HAC troops helped restore order in the City of London; in gratitude the City gave them two brass field‑pieces (small cannons), now prominently displayed in the entrance hall of Armoury House.
 
Interesting facts...
The Medal Room feels like a kind of ghostly gallery: it holds over 400 sets of medals, including those of the HAC’s Victoria Cross recipients, many donated by grieving families who never saw the house itself.  Quite moving
