We reach, next, the last gate in the line of the Harbour Walls, the Gate of Eugenius (Πόρτα τοῦ Εὐγενίου), represented now by Yali Kiosk Kapoussi. Its identity is established by the following indications. It marked the eastern extremity of the fortifications along the Golden Horn,[817] as the Xylo Porta marked their western terminus. Hence, the ditch constructed by Cantacuzene in front of those fortifications is described as extending from the Gate of Eugenius to the Gate Xylinè.[818] In the next place, the gate was close to the head of the promontory, or Acropolis, for ships outward bound rounded the promontory soon after passing the gate, while incoming ships passed the gate soon after rounding the promontory.[819] Again, the Church of St. Paul which stood near the gate is described, as situated in the quarter of the Acropolis, at the opening of the harbour.[820] This is consistent with the fact that the gate was at a point from which St. Sophia could be easily reached.[821] Eugenius, after whom the gate, the adjacent tower, and the neighbouring district were named,[822] was probably a distinguished proprietor in this part of the city. The gate bore an inscription commemorating repairs executed by a certain Julian;[823] possibly, Julian who was Prefect of the City in the reign of Zeno, when Constantinople was shaken by a severe earthquake. There is reason to believe that besides its ordinary designation this gate bore also, at one time, the name Marmora Porta; for certain ecclesiastical documents of the year 1399 and the year 1441 speak of an entrance in the quarter of Eugenius, under the name Marmora Porta, Μαρμαροπόρτα ἐν τῇ ἐνορίᾳ τοῦ Εὐγενίου.[824] The Scala Timasii, so named after Timasius, a celebrated general in the reign of Arcadius, was in the Fourth Region,[825] and must therefore have been a pier near the Gate of Eugenius. At this entrance it was customary for the bride-elect of an emperor to land, upon reaching the capital by sea; here she was received in state by her future consort, and having been invested with the Imperial buskins and other insignia of her rank, was conducted on horseback to the palace.[826] But what lends most interest to the gate is the fact that beside it rose the tower which held the southern end of the chain drawn across the harbour in time of war.[827] Originally, the building, styled Kentenarion (Κεντενάριον), was a stately structure, but after its overthrow by an earthquake, Theophilus restored it as an ordinary tower.[828] The chain was supported in the water by wooden floats,[829] and its northern end was made fast to a tower in the fortifications of Galata, known as the Tower of Galata, “Le Tour de Galatas.”[830] According to Gyllius, the gate near that tower was called Porta Catena,[831] but, unfortunately, he does not indicate its precise position. From the nature of the case, however, it must have been near Kiretch Kapoussi, directly opposite the Gate of Eugenius.[832]
