The name of the gate alluded to the suburb of Pegæ (Πηγαὶ), situated directly opposite, on the northern shore of the harbour, and noted for its numerous springs of water. Dionysius Byzantius, in his _Anaplus of the Golden Horn and the Bosporus_,[727] describes the locality at length, naming it Krenides (Κρηνίδες). on account of its flowing springs (πηγαίων), which gave the district the character of marshy ground. The suburb appears under the name Pegæ in the history of the siege of the city by the Avars, when the Imperial fleet formed a cordon across the harbour, from the Church of St. Nicholas at Blachernæ to the Church of St. Conon and the suburb of Pegæ, to prevent the enemy’s flotilla of boats in the streams at the head of the Golden Horn from descending into the harbour.[728] According to Antony of Novgorod, the suburb was situated to the west of St. Irene of Galata; it contained several churches, and was largely inhabited by Jews.[729] It appears again in the old Records of the Genoese colony of Galata in the fourteenth century, under the name Spiga, or De Spiga, to the west of that town.[730] Critobulus calls it the Cold Waters (Ψυχρὰ Ὕδατα), placing it on the bay into which Sultan Mehemet brought his ships over the hills from the Bosporus.[731] As appears from the passage of the Chronista Novgorodensis, cited above, near the Porta Puteæ stood the Monastery of Christ the Benefactor, interesting as a conspicuous landmark in the scenes associated with the Latin Conquest of the city. The fire which the Venetians set near the portion of the Harbour Walls captured in 1203, reduced to ashes the quarters extending from Blachernæ as far east as that monastery.[732] The monastery marked also the eastern extremity of the line of battle in which the ships of the Crusaders delivered the final attack upon the walls on April 12, 1204;[733] while the fire which illuminated the victory of that day started in the neighbourhood of that religious house, and raged eastwards to the quarter of Drungarius.[734] During the Latin occupation the Venetians established a dockyard on the shore in the vicinity of the monastery;[735] the adjoining district, including the Church of Pantocrator[736] (now Zeirek Klissè Djamissi) and the Church of Pantopoptes[737] (now Eski Imaret Mesdjidi), on the Fourth Hill, being their head-quarters.
