But the modern and ancient streets do not coincide, and the west gate, which has so well withstood the blows of time, can hardly be reached by road from within the city.

At York the defences of the legionary fortress have still their place in the sun, but the 'colonia' on the other bank of the Ouse has vanished wholly from the surface, walls and streets together, and the houses of the citizens of Eburacum are known solely by finds of mosaic floors.

At Lincoln the Roman walls and gates can easily be traced and one gate rears its arch intact, but the Bailgate alone follows, and that erratically, the line of a Roman street.

The road from the Humber, thirty miles north of Lincoln, runs to-day, as it has run for eighteen centuries, under the Newport arch and through the modern town and passes on southwards.

That long straight road has given a feature to Lincoln, but it is a feature due to the Roman highway outside the town, not to the streets within it.
