The Garden to the west of Flamsteed House

By the 1940's, the Observatory's main site at Greenwich occupied an area of 2.46 acres. This section deals only with the garden to the west of Flamsteed House. Other parts of the grounds are covered in the following sections:

The Courtyard
The Astronomers’ Garden
The Meridian Garden
The Magnetic and South Grounds
The Observatory Garden (now part of the Royal Park)
The Christie Enclosure (now part of the Royal Park)

Although occupied since 1911, the slip of ground between the path in the Park and the west wing of Flamsteed House has only been an official part of the Observatory Grounds since 2004.


The boundary moves west

Back in 1675, Flamsteed had a thin strip of garden to the west of the house. In 1791 when the Courtyard was enclosed to the east of the building, the boundary wall to its west was also realigned. The result was a widening of the garden by the width of the Summerhouse (about four metres). The existing garden being elevated above the Park and the boundary wall being a retaining one, a void was created which would have needed to be filled. It was probably at this time, that the Observatory’s second underground cistern was constructed for the storage of rain water. Situated half within the original curtilage, and half within the made up ground, it was located immediately to the south of the western summerhouse (which by then was referred to as the West Dome). The whole of the extended garden was subsequently built over when a new wing was built onto Flamsteed House for Airy in 1835/6.


The boundary moves yet further west

When Dyson was appointed Astronomer Royal in 1910, he required additional accommodation for his family. This was secured by excavating the basement below Airy’s extension. In order to secure a degree of privacy for the new basement rooms, Dyson negotiated a second boundary shift to the west. This is when the present slip of land was enclosed. Normally such an enclosure would have required the issuing of a Royal Warrant; on this occasion however, title to the land was retained by the Park and none was sought.


A question of ownership

In 1953, when a Royal Warrant was signed transferring most of the northern part of the Observatory site to the National Maritime Museum, this slip of land was, as before, retained by the Park. When additional lands on the south side of the Observatory site were later allocated for Museum use, the legal advice from the Treasury Solicitors (who dealt with such matters), was that a Royal Warrant was not needed to legitimise the transfer. None was therefore sought and none was issued. The view of the Treasury Solicitors was re-examined in 1978/0 when security issues relating to fencing and the possible erection of a security building for bag searches were under consideration. Again it was deemed that the Museum's occupation of the landwas legal and that the Warrant did not need amending. The Museum was never terribly happy with this arrangement, so when plans were being developed in the early 2000s to build a new planetarium on the southern part of the Observatory site, it wanted to make doubly sure of its legal right to occupy the land. In light of this, it was arranged for a new Royal Warrant to be issued that once and for all was supposed to adjust and clarify the boundary of the land that the Museum was entitled to occupy. Under the terms of this Warrant (which was signed in 2004), the slip of land transferred from the park to the Museum


Cultivation of the Land

For the past few decades at least, the slip of land has not been cultivated, a dense undergrowth being allowed to build up (as a deterrent to intruders?). Things were rather different when Flamsteed House was still the residence of the Astronomer Royal when the gardens were planted with shrubs and routinely maintained.
