Balmoral is an urban locality in the suburb of Mosman in Sydney, New South Wales, Australia. It is in the local government area of the Municipality of Mosman and is part of the Lower North Shore. The locality is mostly known for its beach, officially divided into Balmoral and Edwards Beaches. Expensive residential real estate on the surrounding "Balmoral Slopes" benefits from the views and beach proximity. The naval depot HMAS Penguin is situated at the eastern end of Balmoral Beach. It houses a naval hospital and is accessed from Middle Head Road. History Balmoral is named after Balmoral Castle, the large estate house in Aberdeenshire, Scotland known as Royal Deeside and a favourite summer royal residence. The Star Amphitheatre, an open-air temple constructed by the Theosophical Society-related group, was built in 1923–1924. Intended as a platform for lectures by the expected "World Teacher", believed by the Theosophists to be Jiddu Krishnamurti, it was demolished in 1951, and its foundations used for an apartment building that still stands on the site. The Balmoral Beach Conservation Area is listed on the New South Wales State Heritage Register. The area includes Edwards Beach as well as Balmoral Beach, plus the promenade, esplanade, rotunda and Bather's Pavilion, which date back to the 1930s. As the Balmoral area developed, it became the location for many examples of the Federation architectural styles that predominated from 1890 to 1915. There are many fine examples of these styles in the area. Balmoral is also the location of Noonee, a heritage-listed home designed by Alexander Stewart Jolly. The house was built 1918-19 and drew on elements of the American hunting lodge. Former tram services The Balmoral line opened as a branch of the Georges Heights line in May 1922 and was one of the last tram lines to be opened in Sydney. Services ran to Wynyard, Lane Cove, Athol Wharf (now Taronga Park Zoo wharf) and Chatswood, making it one of the busiest lines on the North Sydney system. Upon departure from The Esplanade Terminus, at the corner of Mandalong Road, trams travelled south-East along The Esplanade. After passing Botanic Road, the line swung right onto Henry Plunkett Reserve. From this point, the line went off-road onto its own reservation through a narrow rock cutting (now public walking track). After a steep ascent through the reserve, the line crossed several small residential streets such as Mulbring, Gordon, Plunkett,
