Admiralty
It evolved from *Admiralty Navy War Council, (1909–1912) which in turn became the Admiralty War Staff, (1912–1917) before finally becoming the Admiralty Naval Staff in 1917. It was the former senior command, operational planning, policy and strategy department within the British Admiralty. It was established in 1917 and existed until 1964 when the department of the Admiralty was abolished, and the staff departments function continued within the Navy Department of the Ministry of Defence until 1971 when its functions became part of the new Naval Staff, Navy Department of the Ministry of Defence.
Admiralty House, Bermuda
The first location of the Admiralty House had been at "Rose Hill", in St. George's Town, between 1795 and 1806. This was where Irish poet Thomas Moore was employed as a clerk to the Admiralty Court in 1803. St. George's Harbour, up 'til that time, had been the only harbour suitable for large naval vessels that also had a known access route through Bermuda's encircling barrier reef (the Admiralty had plans to utilise Castle Harbour but its shallow waters, and its treacherous entrance through "Castle Roads" proved dangerous in stormy weather). The Royal Navy had begun establishing itself in and around the town, especially at Convict Bay, but had longer term plans for a dockyard and naval base at the opposite end of the archipelago. Royal Naval hydrographers had spent a dozen years in charting the reef, and had discovered a channel that enabled the Royal Navy to begin mooring vessels off the northern shore of St. George's Island at a location that became known as "Murray's Anchorage", after Vice-Admiral Sir George Murray, who led the first fleet to anchor there in 1794. This also opened up the West End of Bermuda, where the Royal Navy had already begun purchasing land around the Great Sound and Hamilton Harbour, to access by large vessels.
