Prince Nicolae Petru mavrogheni (1786-1790) ctitorise "Out to the field, on the outskirts of Bucharest", beyond the head of the Bridge of Mogoşoaiei (the current path of Victory), a complex of buildings that would surround the ruler's Summer Palace. This complex consisted mainly of 3 buildings: the "kiosk" reigns with the related "Chambers", the monastery church and the monks ' barns, namely the "water Treasury", i.e. a reservoir in which the water captured on the Olanas, which then refueled a herd For the use of the Lord's House, another for the use of the "circumstances of the slushers" and a gushing fountain. To these were added three windmills a new Obor "Where to come the inhabitants with those who have for sale" as well as a garden from which later will develop the park Kiseleff. The "Mavroghenesc" Ensemble gave the name of the neighborhood known as "the slum of Mavrogheni's", as it appears in Catagraphy de la 1810 şi în alte documente din secolul al XIX-lea. Încă din vremea domniei lui Nicolae Petru Mavrogheni, pe lângă mănăstire a funcționat o tipografie unde s-au tipărit lucrări emblematice pentru cultura naţională, o şcoală, precum și un spital numit „Filantropia” (al iubirii de oameni), care păstrează până astăzi acelaşi nume.
The Edilitary Opera of the ruler Nicolae Petru Mavrogheni had an ephemeral character. Of all the Mavroghenesti settlements, the only one who kept the memory and the name of his founder is the church. The cult of worship was built in the course of the year 1787, receiving, from the foundation, the "Spring of Healing", as well as the trickling that had been placed under the protection of "The troubles of God and the Virgin of the Sea." Prince Nicolae Petre Mavrogheni worshipped this church to the Ecatontapiliani monastery ("The One with 100 portals") of its native island, Paros, the foundation of the Holy Empress Elena, mother of St. Constantine the Great. In the reign of the ruler we encounter this urge to the followers: Deci pohtim şi pe cei după vremi fraţii domni ce-i va milui Dumnezeu cu domniia aceştii creştineşti ţări să binevoiască a adăoga, a spori şi a ocroti acestea ca unele ce s-au găsit făcute, săvârşite şi puse în faptă şi orânduiala lor. Şi după cum noi ne-am trudit şi le-am făcut acestea din nou, aşa şi frăţiia lor, cu drag să păzescă cele ce găsescu făcute., spre a să urma şi a sta în starea lor, fiind dă folosul obştii, ca să fim împreună împărtăşiţi la pomenire după cuvântul sfintii evanghelii care zice: “And the first mercy and the latter heal. "
The Bierica "Healing Spring" Mavrogheni suffered over time several damage caused by earthquakes, fires or wars, which imposed extensive restoration and consolidation work, sometimes going until the initial architecture was changed. Today, only the Catapeteasma, a unique piece both as architectural value and as an artistical style, also reminds of the old place, built in Baroque style.
