Eagle Aviary at Bristol Zoo, Clifton, City of Bristol

Summary

Aviary. Built in 1962. Designed by Saxon, Smith and Partners. The timber bird houses inserted into the aviary, beneath the canopy, are not included in the listing.

Description

Aviary. Built in 1962. Designed by Saxon, Smith and Partners. The timber bird houses inserted into the aviary, beneath the canopy, are not included in the listing.

MATERIALS: constructed of a central concrete cylinder with laminated Douglas fir timbers and a concrete outer ring wall faced in mosaic tiles. Timber doors and wire mesh netting.

PLAN: a circular aviary with access to a central cylindrical tower, and eight ribs of slightly different height to accommodate the gently sloping site.

DETAILS: a circular aviary formed from a central cylindrical tower, with eight curved ribs that rise from the base of the tower to the perimeter ring and support a circular canopy of five concentric ring beams. The canopy incorporates a central ring of glass domes. The perimeter ring wall at the base of the aviary is formed of concrete faced in blue and white mosaic tiles. From the canopy to the perimeter ring, and from the perimeter ring to the perimeter wall are slender iron struts that together support the wire mesh netting.

Pursuant to s1 (5A) of the Planning (Listed Buildings and Conservation Areas) Act 1990 (‘the Act’) it is declared that the timber bird houses inserted into the aviary, beneath the canopy, are not of special architectural or historic interest, however any works which have the potential to affect the character of the listed building as a building of special architectural or historic interest may still require LBC and this is a matter for the LPA to determine.

History

Bristol Zoological Gardens opened on the 11 July 1836, becoming the second zoological garden to open in England, after London Zoo in Regents Park (1828), and the fifth in Europe; the others being Schönbrunn Zoo in Vienna (1752), the Jardin des Plantes in Paris (1800), and Dublin Zoo (1831). Many more were to follow, illustrating the rapid and extensive establishment of zoological gardens, alongside other C19 cultural institutions such as museums and galleries, that were being built in England and across Europe to exhibit and study the exotic animal, plant, and cultural specimens that were being provided by empire and colonisation.

Bristol Zoological Gardens was founded by The Bristol, Clifton, and West of England Zoological Society that was formed in 1835 with the intention of creating a zoo for the purposes of both education and entertainment. The society raised the funds for their venture through the sale of shares, with many prominent Bristolians, such as Isambard Kingdom Brunel, William Goldney, and members of the Frys, Wills and Sturges families, being among the first shareholders. They were subsequently able to purchase 12 acres of land to the north of the suburb of Clifton on the outskirts of Bristol.

The design for Bristol Zoological Gardens was produced by Richard Forrest. A landscape designer and nurseryman, Forrest, was well-respected in his field and during his career worked on several important commissions including the gardens at Syon House, London, and Eaton Hall, Cheshire, as well as producing designs for several other zoological gardens. As with all early examples of zoological gardens, the design for Bristol was much influenced by the C18 landscaped gardens of the aristocracy, and this can be seen in Forrest’s scheme that retained many of the existing mature trees, but also including the planting of specimen trees and plants, the excavation of a lake to the centre, the creation of a Grand Terrace for promenading, as well as buildings in a characteristic pavilion style. Comparison of Forrest’s plan with George Ashmead’s map of 1853, alongside knowledge of the financial restrictions of the project, suggest that Forrest’s plans were not fully implemented. Ashmead’s map shows a simplified version of Forrest’s scheme with the animal enclosures concentrated to the north of the Grand Terrace, with most of the site being given over to gardens. This would seem to reflect both the difficulty in meeting management costs and that the botanical rather than the animal attractions were the initial draw for visitors. To increase revenue, the site was increasingly hired out for events, becoming a place not only to enjoy the plants and animals, but also a place of entertainment.

From the mid-1850s the surrounding land was developed for housing, and in 1862 the first buildings of Clifton College, located to the immediate south, were built. This development and the later Bank Holiday Act of 1871 led to an increase in visitor numbers leading to extensive changes to the zoo with a clear focus on public entertainment. The new animal enclosures added at this time, such as the elephant and giraffe house, and the polar bear enclosure that abutted its north elevation, were built in domestic styles and reflected the then architectural trend to place foreign wildlife into an English domestic setting.

In the early C20 the zoo suffered a period of stagnation, and the standard of the site declined. However, from 1925, the influence of Dr Richard Clarke as director of the society, began to steer the zoo towards the promotion of knowledge through the quality of the botanical and animal specimens, and away from the pleasure ground aspect of the site. He proposed that 'every year a new feature should be built and shewn annually' to attract increased visitor numbers. He consequently ushered in a new profitability and animal focused philosophy, with the new buildings in modern and interesting settings. These new buildings were often designed under his guidance, with some showing the influence of Carl Hagenbeck’s zoo at Tierpark, Stellingen, near Hamburg (1906), and his ideas for the presentation of animals in their “natural” habitat, with the creation of panoramas, artificial rock formations, and the removal of cages. The Monkey Temple (1928) and the polar bear enclosure (1935) were particular examples at Bristol Zoo.

Further changes occurred throughout the C20 and C21, with a move to more hygienic enclosures with tiled surfaces, to increasingly natural environments as animal welfare and conservation became central to the zoo’s philosophy.

Erected just to the east of The Monkey Temple, the Eagle Aviary was built in 1962 and designed by the Chester-based architectural practice, Saxon, Smith and Partners. Its design, featuring curved laminated timber ribs, and an early example of a glulam structure in an exposed external environment, was intended to suggest the outspread wings of its eagle inhabitants. Some of the ribs formed part of a framework for glass partitions within the aviary, which have since been removed, and the central concrete cylinder was decorated with murals of a mountainous landscape.

Reasons for Listing

The Bird of Prey Aviary at Bristol Zoological Garden, built in 1962 and designed by Saxon, Smith and Partners, is listed at Grade II for the following principal reasons:

Architectural interest:

* as an accomplished example of a 1960s animal enclosure that reflects the architectural design approach of the period to design animal enclosures that reflected the character traits of its inhabitants;
* for its successful merging of traditional aviary design with C20 design principles and materials;
* for its honest and expressive use of materials in an artistic manner, to create a bold architectural form that gives the building a sculptural quality;
* as an early example of a glulam structure in an exposed external environment highlighting both its structural and aesthetic quality as a building material;
* for its good degree of survival.

Historic interest:

* for its illustration of mid-C20 ideas concerning the display of exotic animals and how this informs our understanding of changing architectural approaches and public attitudes to the housing of animals in captivity.

Group value:

* with the other listed buildings at Bristol Zoological Garden.
