These shingles are pointed at the end next the vallum, and broader and squarer at the other end. In the second cutting near the western angle the vallum was found to be 6 feet wide, and below the base there was a layer of imported clay; below this was a layer of red sand 2 feet thick, and under that a quantity of gravel. Here again were found the shingles, of which there were three rows, all lying at right angles to the vallum. The longest of these shingles were from 9 to 14 feet, and were those at the greatest distance from the vallum. Two other cuttings exposed two jambs of a gateway, and the layer of shingles was found to extend from the inside through the gateway to the length of 7 or 8 feet outside; they were larger and longer than any of the others. Under them was a layer of gravel 9 inches thick, and below this, again, a floor of oak planks, smooth and tightly jointed, and stretching across the gateway. Beneath this was another layer of gravel, under which were four large shingles about 14 feet long, 1 foot wide, and 6 inches thick, which were laid at right angles to the shingles above them. On the north-eastern side of the vallum was a strong oak post found standing upright, which appeared to have been a gate-post. In 1725 Dr. Stukeley, the antiquary, visited Ribchester at a time when a portion of the south-eastern boundary was exposed through the action of the river, and he mentions having seen "the floor along the whole bank," which was no doubt made up of similar shingles. The use to which these oak shingles were put has not yet been satisfactorily settled, but the most probable theory is that they were intended to make sure the foundation of the path behind the rampart. They have not been discovered at any other Roman station in Britain. Another peculiarity of the Ribchester camp is the gates being placed in an angle of the quadrilateral instead of in the centre of one of the sides. Outside the camp at Ribchester there was a settlement of considerable size and importance. There were at least two temples, the largest of which was probably over 100 feet long; it had sixteen pillars in front, and others around it, forming a peristyle. The inscription over the entrance (which was found some years ago) shows that it was dedicated "To the Deity: for the safety of the Emperor ... and of Julia ... the mother of our Lord [the Emperor], and the camps under the care of Valerius Crescens Fulvianus, his Legate [and] Pro-Prætor. Titus Floridius Natalis, Legate, our Præpositus and Governor, from the reply [of the oracle] restored the temple from the ground, and inaugurated it at his own expense." The mention of the Empress Julia fixes the date to between A.D. 211 and A.D. 235. The four pillars forming the entrance to the Bull Inn at Ribchester were from the ruins of one of the two temples. The bases of some of the columns of the larger building are preserved at the Rectory; they are of rude workmanship, but appear to be in the Doric style.
