The material composition of the grotto


Much as a composer weaves multiple layers, sounds and rhythms into their work to evoke various emotional connections within the listener or performer, so too the architect has immense control over how people may experience the spaces they design. However the beauty in both a piece of music and in this particular case, the grotto, lies in their ability to evolve beyond the composer’s or architect’s intentions and have meaning bestowed upon them through repeated usage and interpretations or as a result of the aging process. The success of the grotto as a piece of architecture is that the materials used often allow for weathering and decay, which bestow it with greater experiential qualities. Therefore we can construe that for a grotto to be reinterpreted in contemporary architecture, it should reference the materiality or form of the more traditional grottoes.

An authentic grotto is carved out of stone, either by man or nature. However grottoes (or their partner, the Nymphaeum[1]) can also be created within existing buildings, the room being transformed into a cave-like environment, or built from scratch. In this way something that desires to evoke a sense of the grotto should be predominately constructed from stone, or at least reference the jagged elements of natural cave walls.

Tufa and flint were popular stones used to decorate the more elaborate grottoes.[2] With their porous and rugged textures and colour variations, their wildness was exactly what garden designers, particularly those embedded in the British landscaping tradition, sought. Grottoes were seen to be a more authentic element of landscaping “…because they not only represented, but resembled original nature,”[3]and thus were integral to the British landscape gardens of the 18th centuries.

 Figure 1 shows an example of what Tufa can look like.[4]

Another popular decoration is shells,[5] an element of ornamentation that can be interpreted as a symbol of life, through its relationship to the untamed oceans, and its ability to foster crustacean life. However it is likely they were more commonly used as a way demonstrating the owner’s wealth. Similarly, pebbles were often inlaid into the grotto’s walls, benches or embedded underfoot in the floor.[6]

Figure 2, illustrates the complex shell mosaic of the grotto room at Woburn Abbey, 17th Century.[7]

Although the simplest of caves could be treated as a grotto, the more elaborate tended to incorporate sculptures, painting or reliefs of fantastical beings. The preference was towards Classical Greek motifs; nymphs, certain Gods,[8] animals and in Imperial Rome, Odyssean scenes. [9] These statues emphasised the otherworldliness of the space, and enhanced the grotto’s connection with the natural world.

Figure 3, ‘Grotta degli Animali,’ Villa at Castello, circa 1538.[10]

Light is another key component of a grotto. It is the different effects of lighting that can be used to create a highly experiential environment. The cave is a naturally dark space, with light filtering in through the cavern’s mouth. Water and ornamentation such as pieces of mirror reflects what little light there may be in a grotto, transforming the grotto into a space of otherworldly illusion.[11] Bowe observes that in ancient Greece the “aura of a cave, the dim, imperfect light…and the shadows cast by torches or fires lit to illuminate the interiors must have served to intensify the experience,” of these sacred spaces. Similarly in the renaissance and British landscaping traditions the play of light helped evoke a sense of the cosmos,[12] particularly when reflective materials were embedded in the ceiling, a reminder of the night sky.[13]

Perhaps the most essential component of the grotto asides from its preferably cavernous setting is water. Water, a common metaphor for life, was seen as a natural element of the cave. To the ancient Greeks water was sacred, and “the sound of water as it rose and fell and struck the floor” would have only enhanced the divinity of the grotto.[14] Water often has an important role in naturally eroding stones to create cavernous spaces, materials like tufa and also fosters the growth of moss, which will often adorn walls of the grotto.




With the advent of water engineering the grotto rapidly became an even more theatrical space, featuring man-made fountains, pools and waterfalls with the intent of evoking “wonder and surprise.”[15] After all it was only natural that the statues of nymphs be depicted frolicking in water, their preferred element. As referenced in my first post, Villa d’Este is perhaps one of the most famous grottoes to extensively utilise water in order to achieve such awe and illusion.[16]

Although such examples of ornamentation, and use of materials in grotto-inspired architecture today have fallen from fashion, contemporary examples still exist that pay homage to some of the more complex traditional grottoes. ARM’s Storey Hall, despite the absence of water symbolism, is a public building that clearly references the grotto in its ornamentation. It’s organic and jagged façade, and cave-like entrance, assisted by its motley purple and green colour scheme seems to be an abstraction of the moss-hewn walls of traditional grottoes. This architectural language is continued through the interior, with the faceted paneling representing the stone surface of a cave, and the detail within each panel reminiscent of the shell and pebble mosaics.

Where other architects steer clear of ornamenting their grotto-inspired architectural compositions, instead often focusing on complex computer-generated organically inspired models, ARM celebrates the cave through its complex decorative motifs. This supports my argument that one can re-appropriate some of the more traditional elements of grottoes into contemporary design language.
