Orangery


An orangery or orangerie is a room or dedicated building, historically where orange and other non-hardy fruit trees are protected during the winter, as a large form of greenhouse or conservatory. In the modern day an orangery could refer to either a conservatory or greenhouse built to house fruit trees, or a conservatory or greenhouse meant for another purpose.
The orangery provided a luxurious extension of the normal range and season of woody plants, extending the protection which had long been afforded by the warmth offered from a masonry fruit wall. During the 17th century, fruits such as oranges, pomegranates, and bananas arrived in huge quantities at European ports. Since these plants were not adapted to the harsh European winters, orangeries were invented to protect and sustain them. The high cost of glass made orangeries a status symbol showing wealth and luxury. Gradually, due to technological advancements, orangeries became more of a classic architectural structure that enhanced the beauty of an estate garden, rather than a room used for wintering plants.
The orangery originated from the Renaissance gardens of Italy, when glass-making technology enabled sufficient expanses of clear glass to be produced. In the north, the Dutch led the way in developing expanses of window glass in orangeries, although the engravings illustrating Dutch manuals showed solid roofs, whether beamed or vaulted, and in providing stove heat rather than open fires. This soon created a situation where orangeries became symbols of status among the wealthy. The glazed roof, which afforded sunlight to plants that were not dormant, was a development of the early 19th century. The orangery at Dyrham Park, Gloucestershire, which had been provided with a slate roof as originally built about 1702, was given a glazed one about a hundred years later, after Humphrey Repton remarked that it was dark; although it was built to shelter oranges, it has always simply been called the "greenhouse" in modern times.
The 1617 Orangerie at the Palace of the Louvre inspired imitations that culminated in Europe's largest orangery, the Versailles Orangerie. Designed by Jules Hardouin-Mansart for Louis XIV's 3,000 orange trees at Versailles, its dimensions of were not eclipsed until the development of the modern greenhouse in the 1840s, and were quickly overshadowed by the glass architecture of Joseph Paxton, the designer of the 1851 Crystal Palace. His "great conservatory" at Chatsworth House was an orangery and glass house of monumental proportions.
The orangery, however, was not just a greenhouse but a symbol of prestige and wealth and a garden feature, in the same way as a summerhouse, folly, or "Grecian temple". Owners would conduct their guests there on tours of the garden to admire not only the fruits within but also the architecture outside. Often the orangery would contain fountains, grottos, and an area in which to entertain in inclement weather.

Earliest examples

As early as 1545, an orangery was built in Padua, Italy. The first orangeries were practical and not as ornamental as they later became. Most had no heating other than open fires.
In England, John Parkinson introduced the orangery to the readers of his Paradisus in Sole, under the heading "Oranges". The trees might be planted against a brick wall and enclosed in winter with a plank shed covered with "cerecloth", a waxed precursor of tarpaulin, which must have been thought handsomer than the alternative:
For that purpose, some keep them in great square boxes, and lift them to and fro by iron hooks on the sides, or cause them to be rowled by trundels, or small wheeles under them, to place them in a house or close gallery.

The building of orangeries became most widely fashionable after the end of the Eighty Years' War in 1648. The countries that started this trend were France, Germany, and the Netherlands, these countries being the ones that saw merchants begin importing large numbers of orange trees, banana plants, and pomegranates to cultivate for their beauty and scent.

Construction materials

Orangeries were generally built facing south to take advantage of the maximum possible light, and were constructed using brick or stone bases, brick or stone pillars, and a corbel gutter. They also featured large, tall windows to maximise available sunlight in the afternoons, with the north facing walls built without windows in a very heavy solid brick, or occasionally with much smaller windows to be able to keep the rooms warm. Insulation at these times was one of the biggest concerns for the building of these orangeries, straw became the main material used, and many had wooden shutters fitted to keep in the warmth. An early example of the type of construction can be seen at Kensington Palace, which also featured underfloor heating.
Contemporary domestic orangeries are also typically built using stone, brick, and hardwood, but developments in glass, other materials, and insulation technologies have produced viable alternatives to traditional construction. The main difference with a conservatory is in the construction of its roof – a conservatory will have more than 75 per cent of its roof glazed, while an orangery will have less than 75 per cent glazed. Domestic orangeries also typically feature a roof lantern. Improved design and insulation has also led to an increasing number of orangeries that are not built facing south, instead using light maximising techniques to make the most of available natural sunlight.

Early orangeries

The first examples were basic constructions and could be removed during summer. Notably not only noblemen but also wealthy merchants, e.g., those of Nuremberg, used to cultivate citrus plants in orangeries. Some orangeries were built using the garden wall as the main wall of the new orangery, but as orangeries became more and more popular they started to become more and more influenced by garden designers and architects, which led to the connection between the house and architectural orangery design. This became further influenced by the increased demand for beautiful exotic plants in the garden, which could be grown and looked after in the orangeries.
This created the increased demand in garden design for the wealthy to have their own exotic private gardens, further fuelling the status of the orangery becoming even more the symbol of the elite. This in turn created the need for orangeries to be constructed using even better techniques such as underfloor heating and the ability to have opening windows in the roofs for ventilation. Creating microclimates for the propagation of more and more exotic plants for the private gardens that were becoming creations of beauty all around Europe.

The orangery built adjacent to Kensington Palace, believed to be designed by Nicholas Hawksmoor, was constructed between 1704 and 1705.
The orangery at the Royal Botanic Gardens, Kew, was designed in 1761 by Sir William Chambers and at one time was the largest glasshouse in England.
The orangery at Margam Park, Wales, was built between 1787 and 1793 to house a large collection of orange, lemon, and citron trees inherited by Thomas Mansel Talbot. The original house has been razed, but the surviving orangery, at, is the longest one in Wales.
An orangery dating from about 1700 is at Kenwood House in London, and a slightly earlier one at Montacute. Other orangeries in the hands of the National Trust include:
  • Ham House, Richmond, Surrey, in brick, a somewhat less fancy building than others, placed at the end of the walled kitchen garden.
  • Hanbury Hall, Worcestershire
  • Croome Court, called the "Temple Greenhouse"; an elaborate Roman temple facade designed by Robert Adam in 1761.
  • Ickworth House, Suffolk, where it forms part of the garden front of the dwelling wings
  • Powis Castle, Montgomeryshire, a central feature on the late-18th-century terraces
  • Saltram House, Devon, probably to a Robert Adam design
  • Seaton Delaval Hall, Northumberland
  • Blickling, Norfolk
  • Gibside, in Gateshead, near Newcastle-upon-Tyne, now a ruined shell
In 1970, Victor Montagu constructed an orangery in his formal Italianate gardens at Mapperton, Dorset.
A mid-19th-century orangery at Norton Hall in Sheffield, England, has been converted to apartments.
In Ireland, orangeries were built at Killruddery House and Loughcrew House.
