Coordinates: The Frogmore Estate or Gardens comprise 33 acres (130,000 m2) of private gardens within the grounds of the Home Park, adjoining Windsor Castle, in the English county of Berkshire. The name derives from the preponderance of frogs which have always lived in this low-lying and marshy area.
It is the location of Frogmore House, a Royal retreat. It is also the site of three burial places of the British Royal Family: the Royal Mausoleum containing the tombs of Queen Victoria and Prince Albert; the Duchess of Kent's Mausoleum, burial place of the Queen Victoria's mother; and the Royal Burial Ground.
Frogmore House 
Places of Burial 
Duchess of Kent's Mausoleum 
This mausoleum within the Frogmore Gardens is the burial place of Queen Victoria's mother, Victoria of Saxe-Coburg-Saalfeld, the Duchess of Kent. The Mausoleum was designed by the architect A J Humbert, to a concept design by Prince Albert's favourite artist, Professor Ludwig Gruner.
In the latter years of her life, the Duchess lived in Frogmore House and in the 1850s, construction began on a beautiful domed 'temple' in the grounds of the estate. The top portion of the finished building was intended to serve as a summer-house for the Duchess during her lifetime, while the lower level was destined as her final resting place. The Duchess died at Frogmore House on 16 March 1861 before the summer-house was completed so the upper chamber became part of the mausoleum and now contains a statue of the Duchess.
Royal Mausoleum (or 'Frogmore Mausoleum') 
The second mausoleum in the grounds of Frogmore, just a short distance from the Duchess of Kent's Mausoleum is the very much larger Royal Mausoleum, the burial place of Queen Victoria and her consort, Prince Albert.
Queen Victoria and her husband had long intended to construct a special resting place for them both, instead of the two of them being buried in one of the traditional resting places of British Royalty, such as Westminster Abbey or St. George's Chapel, Windsor. The mausoleum for the Queen's mother was being constructed at Frogmore in 1861 when Prince Albert died in December of the same year. Within a few days of his premature death, proposals for the mausoleum were being drawn up by the same designers involved in the Duchess of Kent's Mausoleum: Professor Gruner and A J Humbert.
Work commenced in March 1862. The dome was made by October and the building was consecrated in December 1862, although the decoration was not finished until August 1871.
The building is in the form of a Greek cross. The exterior was inspired by Italian Romanesque buildings, the walls are of granite and Portland stone and the roof is covered with Australian copper. The interior decoration is in the style of Albert's favourite painter, the Renaissance genius Raphael, an example of Victoriana at its most opulent. The interior walls are predominantly in Portuguese red marble, a gift from King Luis I of Portugal, a cousin of both Victoria and Albert, and are inlaid with other marbles from around the World.
The monumental tomb itself was designed by Baron Carlo Marochetti. It features recumbent marble effigies of the Queen and Prince Albert. The sarcophagus was made from a single piece of flawless grey Aberdeen granite. The Queen's effigy was made at the same time, but was not put in the mausoleum until after her funeral.
Only Victoria and Albert are interred there, but the mausoleum contains other memorials. Among those is a charming monument to Princess Alice, Grand Duchess of Hesse-Darmstadt (1843–1878), Victoria's second daughter, who died of diphtheria shortly after her youngest daughter May (1874–1878). In the centre of the chapel is a monument to Edward, Duke of Kent, Victoria's father. He died in 1820 and is buried in St George's Chapel, Windsor.
One of the sculptures is of Queen Victoria and Prince Albert in Saxon Dress  executed by William Theed (1804-91). The official guidebook includes an image of the sculpture (but not of the pedestal), and mentions that the Queen recorded in her diary that the idea for it came from Victoria, Princess Royal (her eldest child) and that the inscription on the plinth is a quotation from The Deserted Village by Oliver Goldsmith.  The inscription on the plinth alludes to the poet's lament for the passing of the imagined village of 'Sweet Auburn'.
Royal Burial Ground 
Among those buried there are Prince Arthur, Duke of Connaught, and Prince Henry, Duke of Gloucester, as well as Prince George, Duke of Kent. It is also the resting place of Queen Maria of Yugoslavia, a great-granddaughter of Queen Victoria and wife of King Aleksandar I of Yugoslavia, the Duke of Windsor, who reigned as King Edward VIII before abdication; and his wife Wallis. Many members of the families of Prince Christian of Schleswig-Holstein and of the Marquess of Cambridge are also buried there.
Other garden features 
Also within the grounds lie various garden buildings and monuments, including the 'Gothic Ruin' (1793), 'Queen Victoria's Tea House' (a brick pavilion building of 1869) and the 'Indian Kiosk' commemorating the end of the Indian Mutiny (1858).
Public access 
The house, gardens and Royal mausoleum are usually open to the public about six individual days each year, usually around Easter and the August Bank Holiday. The mausoleum is also usually open on the Wednesday nearest Queen Victoria's birthday, 24 May. The mausoleum has not opened to the public since 2008. It has been closed continually because of an ongoing long-term conservation project and remains closed in 2013. The Royal Burial Ground may be viewed from around its perimeter on the days that the gardens are open to the public. The Duchess of Kent's mausoleum may also be viewed externally, but is never open to the public.
