The elegance of some of the enamelled brooches and rings, together with other discoveries, point to a considerable degree of luxury and civilisation. One writer fancied that he detected the remains of raised seats for spectators at a circus or amphitheatre in the so-called Martyr's Field, near the London, Chatham, and Dover Railway Station. The exact dimensions and extent of the city are open to some doubt. Mr T. Godfrey Faussett fixed the site of the four gates as follows:--(1) _Worth Gate_, at the end of Castle Street; (2) _Riding Gate_, on the old road to Dover; (3) _North Gate_, near the present south-west tower of the Cathedral; and (4) a gate _at the Ford_, in Beer Cart Lane. Tracing the walls that lie between them, he concluded that the shape of the Roman town was an irregular oval, different from the usual square or rectangle, but accounted for by the low swampy ground that surrounded it, and not unlike the shape of Verulam and Anderida. The city's length, according to his plan, must have been nearly exactly double its breadth--namely 800 yards by 400. [Illustration: FROM A PLAN DRAWN BY T. GODFREY FAUSSETT.] For actual existing buildings that may possibly have been connected with the Roman occupation, we must have recourse to the _churches_, which supply us with traces of early Christianity more rich and numerous than that of any other town in England. These are to be found in St. Martin's, St. Pancras, and a church on the site of the present Cathedral. Detailed investigation of them would bring us to some controversial points, for the discussion of which one must be thoroughly conversant with all the recent discoveries and explorations that have been made. But we may, at any rate, state the _documentary_ evidence. With regard to _St. Martin's_ Church, we have already quoted the statement made by the Venerable Bede. The same historian also informs us that Augustine, "when the Episcopal See was granted to him in the royal city, recovered therein, supported by the king's assistance, a church which, he was informed, had been built by the ancient work of Roman believers; and consecrated it in the name of our Holy Saviour, God and Lord, Jesus Christ."
