A grotto or grot is a natural or artificial cave or covered recess. Naturally occurring grottoes are typically small coastal caves associated with bodies of water and may be partially or fully submerged at high tide. Artificial grottoes have also been constructed as garden features, particularly in landscape design from the Renaissance onward. WellâÂÂknown natural examples include the Grotta Azzurra on Capri and the grotto at Tiberiusâ Villa Jovis in the Bay of Naples.
The word grotto derives from Italian grotta, from Vulgar Latin grupta, and ultimately from Latin crypta (âÂÂcryptâÂÂ). The term is also historically connected to grotesque. In the late 15th century, the buried rooms of NeroâÂÂs Domus Aurea on the Palatine Hill were rediscovered. Their sunken, caveâÂÂlike condition led Renaissance viewers to describe the decorative motifsâÂÂgarlands, slender architectural frameworks, foliage, and animalsâÂÂas grottesche, a term that subsequently gave rise to the French grotesque.
Grottoes were prominent features in Greek and Roman culture. SpringâÂÂfed grottoes formed part of the oracular sanctuaries of Apollo at Delphi, Corinth, and Clarus. In the Hellenistic period, the city of Rhodes incorporated rockâÂÂcut artificial grottoes into its urban design, conceived to resemble natural formations. At the Roman sanctuary of Praeneste, the earliest part of the complex was located on the second lowest terrace, in a natural grotto where a spring developed into a well. According to tradition, the sacred spring was associated with a local nymph, who was venerated in a grottoâÂÂlike watery nymphaeum.
The popularity of artificial grottoes helped introduce the Mannerist aesthetic into Italian and French gardens of the midâÂÂ16th century. Two celebrated examples in the Boboli Gardens at the Palazzo Pitti were begun by Giorgio Vasari and completed by Bartolomeo Ammanati and Bernardo Buontalenti between 1583 and 1593; one originally housed MichelangeloâÂÂs Prisoners. Earlier, at the Medici Villa Castello near Florence, Niccolò Tribolo had incorporated a grotto into the garden layout. At the nearby Pratolino, despite the dryness of the site, a surviving Grotto of Cupid featured water tricks designed to surprise visitors. The Fonte di Fata Morgana at Grassina (1573âÂÂ74), built within the grounds of Bernardo VecchiettiâÂÂs Villa âÂÂRiposoâÂÂ, is a small garden pavilion decorated with sculptures in the Giambologna manner.
The outsides of garden grottoes were often designed to resemble an enormous rock, a rustic porch, or a rocky overhang. Interiors could evoke temples or watery caverns, decorated with fountains, stalactites, imitation gems and shells, herms, mermaids, and naiads whose urns spilled water into pools. Damp grottoes offered a cool retreat from the Italian sun, but they also became fashionable in the cooler climate of the ÃÂle-de-France. At the Kuskovo Estate, the Grotto Pavilion was built between 1755 and 1761.
Grottoes could also serve as baths, as at the Palazzo del Te, where the 'Casino della Grotta' contains a suite of intimate rooms arranged around a grotto and loggetta. Courtiers once bathed beneath a small cascade splashing over pebbles and shellâÂÂencrusted walls. Grottoes also functioned as chapels or, at Villa Farnese in Caprarola, as a small theatre designed in the grotto manner. They were frequently combined with cascading fountains in Renaissance gardens.
The grotto designed by Bernard Palissy for Catherine de' MediciâÂÂs château in the Tuileries was renowned. Grottoes also appeared in the gardens designed by André Le Nôtre for Versailles. In England, an early garden grotto was built at Wilton House in the 1630s, probably by Isaac de Caus.
Grottoes were incorporated into less formal garden designs as well. Pope's Grotto, created by Alexander Pope at Twickenham, is almost all that survives of one of the earliest landscape gardens in England. Pope was inspired by grottoes he had seen in Italy, and restoration efforts are ongoing. Grottoes also feature in the landscape gardens of Painshill Park, Stowe, Clandon Park, and Stourhead. Scott's Grotto in Ware, Hertfordshire is a lateâÂÂ18thâÂÂcentury complex of chambers extending 20 metres into a chalk hillside, lined with shells, flints, and coloured glass. During the Romantic period, Fingal's Cave on Staffa became widely known through literary and musical references, notably Felix MendelssohnâÂÂs Hebrides Overture. In the 19th century, when miniature mountains and rock gardens became fashionable, grottoes were often included, as at Ascott House. In Bavaria, Ludwig IIâÂÂs Linderhof contains an evocation of the Venusberg grotto from Richard WagnerâÂÂs Tannhäuser.
Although grottoes have largely fallen from fashion since the British Picturesque movement, architects and artists have occasionally reinterpreted the grotto in contemporary design. Examples include Frederick KieslerâÂÂs Grotto of Meditation for New Harmony (1964), ARMâÂÂs postâÂÂmodern Storey Hall (1995), Aranda/LaschâÂÂs Grotto Concept (2005), DSDHAâÂÂs Potters Field Park Pavilions (2008), and Callum MoretonâÂÂs Grotto pavilion (2010). A further example is Antonino CardilloâÂÂs Grottoes series (2013âÂÂ2016), which explores the grotto as a contemporary architectural archetype.
Artificial grottoes are widely constructed for ornamental and devotional purposes, often serving as shrines that house statues of saints, particularly the Virgin Mary. These structures are commonly found in gardens, church grounds, and other outdoor settings.
Many Roman Catholics visit the grotto at Lourdes, where Bernadette Soubirous reported apparitions of the Virgin Mary. Numerous modern garden shrines are modeled on this site, and replicas of the Lourdes grotto can be found in churches and religious institutions around the world.
One of the largest devotional grotto complexes is the Grotto of the Redemption in West Bend, Iowa, a monumental assemblage of stone, minerals, and religious sculpture.
In Ticino, the Italian-speaking part of Switzerland, grottoes were places where wine and food were stored and preserved. They were built by exploiting the morphology of rocks and boulders, to create rooms with a cool climate suitable for food, particularly milk and cheese, as well as potatoes, sausages, and wine storage.
The importance of these cellars is demonstrated in their number; for example, there are 40 grotti in Maggia, no fewer in Moghegno, and about 70 in Cevio behind Case Franzoni. Some grotti have been opened to the public, as in Avegno, but most have lost their original character as they became rustic restaurants which serve basic local food and drink. A true grotto is dug out under a rock or between two boulders, where subterranean air currents keep the room cool. Often a grotto had a second floor with another one or two rooms for the fermentation cask and tools of the vintage. In front of the grotto were a table and benches of stone, where the farmers could rest and refresh themselves.
