A lavra or laura (Greek: Λαύρα; Cyrillic: Ла́вра) is a type of monastery consisting of a cluster of cells or caves for hermits, with a church and sometimes a refectory at the center. It is erected within the Orthodox and other Eastern Christian traditions. The term is also used by some Roman Catholic communities. The term in Greek initially meant a narrow lane or an alley in a city.
The Greek term lavra was employed from the fifth century on specifically for the semi-eremitical monastic settlements of the Judean desert, where lauras were very numerous. The first lauras of Palestine were founded by St. Chariton (born 3rd century, died ca. 350): the Laura of Pharan (northeast of Jerusalem), the Laura of Douka (west of Jericho) and Souka Laura or Old Laura in the area of the Tekoa Valley.
Saint Euthymius the Great (377-473) founded one of the early Lavras in fifth-century Palestine. The Lavra of Saint Sabbas the Sanctified (†532), known as Mar Saba, is one of the most ancient and almost continuously functioning monasteries in the Christian Church.
DE "firstname.lastname@example.org" entre le milieu du Vème et le début du VI ème SAINT BUDOC (le même que le SAINT de BUDOC WATER à coté de FALMOUTH) s'établit à l'EST de l'ile de BREHAT (cotes d'armor , bretagne, France) l'ile où il batit son ABBAYE-ECOLE s'appelle LAVRA (cf : le cartulaire de LANDEVENNEC) d'où est issu "LAVRE". C'est la première ABBAYE Bretonne en ARMORIK. Des restes , très humbles, sont encore visibles, sous le maquis . Mais ces restes sont sur un terrain communal, donc "visitable". Les moines celtes dont "le pére très haut" qu'était BUDOC avaient des informations précises sur les habitudes, les moeurs des premiers chrétiens coptes voir des anachorètes du temps des pharaons. (la vie en cellules dispersée. Puis les LAURES ((cellules autour d'une rue centrale)), LA TONSURE des pères du désert)(cf: Arthur LE MOYNE de LA BORDERIE , histoire de la BRETAGNE)
A similar system was established in the Jordan Valley in the middle of the fifth century by Saint Gerasimus, with 70 cells surrounding a cenobium, again with monks progressing into the cells after time spent in the coenobium. Weekdays were spent in the cells, accompanied only by a rush mat, a small amount of food and palm blades with which to make ropes and baskets. On Saturdays they would bring their handiwork to the coenobium and receive communion together, returning to their cells on Sunday evening. Cells were left open, and those in need could take whatever they wished from the cell if it were found empty. The lavra had a priest, the lavra’s contact with the outside world, and at least two ordained deacons.
Some modern Coptic authors, and they alone, already apply the specific Greek term lavra to even earlier monastic settlements from the Nitrean desert and even attribute the writing down of the formal rules of a lavra to the Egyptian sanctified monk Macarius the Great in AD 330. Unless proven otherwise by future scholarship, this opinion seems to be theirs alone.
Their claim is that the lavrite style of living has its origins in the early fourth century, by equating the creation of the first lavras with the founding of a settlement of cells in the Nitrean desert at a site known as Nitria, named for the nearby town of the same name. It was a community of 600 hermits who lived scattered over the area, reliant on the town of Nitria for bread, but with their own priest and church. 
The largest and the most important Russian Orthodox monasteries have been called lavras and have been subordinated directly to the Patriarch of Moscow. In 1721, they became subordinated to the Holy Synod.
