A third example may be drawn from our own country. Lincoln, the Roman Lindum, was established as a 'colonia' about A.D. 75, and the lines of its original area, its 'Altstadt'--for it was perhaps enlarged in Roman times,--can still be traced 'Above Hill' round the Castle and Cathedral (fig. 26). It formed a rectangle just over 41 acres in extent (400 x 500 yds.). Four gates, one of which still keeps its Roman arch, gave access to the two main streets which divided the town into four symmetrical quarters and crossed at right angles in the centre. Along one of these streets, which agrees, if only roughly, with the modern Bailgate, ran a stately colonnade (fig. 27), though whether this belonged to some special building or adorned the whole extent of street is not quite certain. Beneath the same street ran, as at Timgad and Laibach and elsewhere, the town sewer (fig. 28). Of the other main street and of side streets nothing is known, but we can hardly doubt that they carried out the chess-board pattern.[101] [101] _Archaeologia_, liii. 236 and lvi. 371. The plan given by Mr. Fox in liii. 236 represents his own theory, which may be open to doubt. Probably the other four municipalities in Britain were planned similarly, though the evidence is too slender to prove it. At Verulamium (for example) near St. Albans, a local archaeologist long ago claimed to detect a scheme of symmetrical house-blocks, resembling squares very slightly askew. Subsequent inquiry has shown that this scheme was merely or mostly imagination.[102] [102] J.W. Grover, _Brit. Archaeol. Assoc. Journal_, xxvi. (1870), p. 45, plate 1. The theories of the late Mr. Bellows about the streets of Roman and modern Gloucester were equally astray, though in other ways. [Illustration: FIG. 28. LINCOLN. SEWER UNDER BAILGATE] CHAPTER IX ROMAN PROVINCIAL TOWN-PLANS. II In the preceding chapters Roman town-planning has been treated in connexion with towns of definite municipal rank, which bore the titles 'colonia' or 'municipium'. The system is, of course, closely akin to such foundation or refoundation as the establishment of a 'colonia' implied in the early Empire, while the no less Roman character of the 'municipium' made town-planning appropriate to this class of town also.
