_Ibid._, p. 423. Dr. Mordtmann (pp. 73, 74) identifies the Monastery of Christ the Benefactor with the ruined Byzantine church known as Sinan Pasha Mesdjidi, to the south of St. Theodosia (see Dr. Paspates, pp. 384, 385). But the prominence of the monastery suggests a position nearer the shore. For incidents connected with it, see Pachymeres, vol. ii. p. 579; Cantacuzene, iii. p. 493. A tower near the monastery (“ab ultima turri de Virgioti versus Wlachernam”) marked the eastern limit of certain fishery rights in the Golden Horn granted to the Monastery of St. Giorgio Majore, at Venice (_Tafel und Thomas_, ii. pp. 47-49). CHAPTER XV. THE WALLS ALONG THE GOLDEN HORN—_continued_. The next gate on the list of Pusculus and Dolfin is the Porta Platea, or Porta ala Piazza,[738] evidently the Porta of the Platea (Πόρτα τῆς Πλατέας) mentioned by Ducas.[739] The entrance, judging by its name, was situated beside a wide tract of level ground, and is, consequently, represented by Oun Kapan Kapoussi, which stands on the plain near the Inner Bridge, at the head of the important street running across the city from sea to sea, through the valley between the Fourth and Fifth Hills. The district beside the gate was known as the Plateia (Πλατεῖα),[740] and contained the churches dedicated respectively to St. Laurentius and the Prophet Isaiah.[741] The blockade of the Harbour Walls in 1453 by the Turkish ships in the Golden Horn extended from the Xylo Porta to the Gate of the Platea.[742] If the legend on Bondelmontius’ map may be trusted, this gate bore also the name Mesè, the Central Gate, a suitable designation for an entrance at the middle point in the line of the harbour fortifications.
