As today marks — depending on how you look at it — the 60th anniversary of the death of the Last Emperor of India, or the Accession to the Throne of Queen Elizabeth II, there will be ceremonial gun salutes held at lunchtime.

Hyde Park will fire 41 rounds — 21 for Her Majesty and 20 because it is a Royal Park. The salute is fired by The King’s Troop, Royal Horse Artillery and starts at 12 noon today.

The Salutes take place in the park, slightly to the South-West of Speakers Corner.

An hour later at 1pm, the Honourable Artillery Company will fire 62 rounds at the Tower of London — 21 for Her Majesty, 20 because it is a Royal Fortress and another 21 for the City of London.

The Salute takes place on the riverside, and because it is quite a narrow space, the best place to watch is actually from Tower Bridge, unless you arrive very early to get up close.
