Saint Catherine’s Monastery: il monastero cristiano abitato senza interruzione da 1.500 anni, edificato attorno al Roveto Ardente

Il monastero di Santa Caterina fu costruito tra il 548 e il 565 per volere dell’imperatore bizantino Giustiniano I, che vi fece racchiudere la Cappella del Roveto Ardente — già fatta erigere in precedenza dall’imperatrice madre Elena — nel luogo dove, secondo la tradizione, Mosè vide il roveto che bruciava senza consumarsi. La prima testimonianza scritta della vita monastica sul Sinai risale al diario di viaggio della pellegrina Egeria, degli anni 381-386. Ancora oggi, dietro l’altare maggiore della basilica, sopravvive un rovo secolare identificato come il Roveto Ardente biblico: per accedere alla cappella che lo custodisce, i visitatori devono togliersi le scarpe, come Dio comandò a Mosè. La biblioteca del monastero, fondata nello stesso periodo, è riconosciuta dal Guinness dei Primati come la più antica biblioteca al mondo ancora in funzione, e custodisce la seconda collezione di codici e manoscritti antichi più grande al mondo dopo quella della Biblioteca Vaticana — tra cui, fino alla sua scoperta e rimozione da parte dello studioso tedesco Constantin von Tischendorf nel 1844 e nel 1859, il Codex Sinaiticus, un manoscritto greco del IV secolo tra le più antiche Bibbie complete sopravvissute.

About Saint Catherine’s Monastery

Saint Catherine’s Monastery, built between 548 and 565 CE by order of the Byzantine Emperor Justinian I, is widely recognised as the oldest continuously inhabited Christian monastery in the world. Justinian’s construction enclosed the earlier Chapel of the Burning Bush, also known as Saint Helen’s Chapel, which had been ordered built by Empress Helena, mother of Constantine I, at the traditional site where Moses is said to have encountered the burning bush that spoke to him without being consumed by fire. The earliest documented evidence of monastic life on Mount Sinai comes from the Itinerarium Egeriae, a travel journal written in Latin by a female Christian pilgrim named Egeria, likely from the Atlantic coast of Galicia or Roman Gaul, recording her journey to the region between roughly 381 and 386 CE. The monastery’s centuries-old bramble, still growing behind the basilica’s main altar within the Chapel of the Burning Bush, is venerated as the biblical burning bush itself; visitors must remove their shoes before entering the chapel, echoing the divine command given to Moses in the Book of Exodus. The monastery’s library, founded in the same period as the wider complex between 527 and 565 CE, is recognised by Guinness World Records as the oldest continuously operating library anywhere in the world, and preserves the second-largest collection of early codices and manuscripts on earth, surpassed only by the Vatican Library. Its holdings, spanning Greek, Syriac, Georgian, Coptic, Armenian, Arabic, Ottoman Turkish, Ethiopic, and Old Church Slavonic texts, include Bibles, patristic writings, liturgical books, and legal documents. Among these treasures, the library’s most celebrated holding was the Codex Sinaiticus, a 4th-century Greek manuscript of the Christian Bible and one of the oldest surviving complete Bibles in existence, discovered at the monastery by the German scholar Constantin von Tischendorf during visits in 1844 and 1859.

History

Saint Catherine’s Monastery’s continuous occupation across nearly one and a half millennia, surviving the rise and fall of the Byzantine, Islamic, Crusader, Ottoman, and modern political orders that successively controlled the Sinai Peninsula, makes it an almost unparalleled case of institutional religious continuity anywhere in the world. Its direct physical connection to the biblical narrative of Moses and the burning bush situates the monastery at one of the most sacred intersection points shared by Judaism, Christianity, and Islam, a status reflected in the monastery’s historically documented protections from successive Muslim rulers.

The monastery’s library, holding the world’s second-largest collection of ancient manuscripts and once home to the Codex Sinaiticus, represents an extraordinary and continuously accessible repository of early Christian and broader Mediterranean intellectual history, its Guinness-recognised status as the world’s oldest operating library underscoring the sheer unbroken duration of scholarly and religious activity sustained at this remote desert site.

What you see

The monastery’s massive granite fortification walls, built under Justinian’s direct orders in the 6th century, enclose the basilica, the Chapel of the Burning Bush, the historic library, and a small Fatimid-era mosque built within the walls for the protection of the community. The still-living bramble venerated as the burning bush grows directly behind the basilica’s main altar, while the surrounding walls and gardens preserve the monastery’s continuous inhabitation across nearly fifteen centuries at the base of Mount Sinai.
