"It may be noted that this enclosure presents not the slightest appearance of a motte. It is at a lower level than the body of the hill, and belongs most certainly to the Edwardian period of the masonry buildings." [Illustration: FIG. 4. Eddisbury, Cheshire. Witham, Essex.] WARWICK Castle has a motte which has been confidently attributed to Ethelfleda, only because Dugdale copied the assertion of Thomas Rous, a very imaginative writer of the 15th century, that she was its builder. The borough which Ethelfleda fortified probably occupied a smaller area than the mediæval walls built in Edward I.'s reign; and it is probable that it did not include the site of the castle, as Domesday states that only four houses were destroyed when the castle was built.[84] The borough was doubtless erected to protect the Roman road from Bath to Lincoln, the Foss Way, which passes near it. Domesday Book, after mentioning that the king's barons have 112 houses in the borough, and the abbot of Coventry 36, goes on to say that these houses belong to the lands which the barons hold outside the city, and are rated there.[85] This is one of the passages from which the late Professor Maitland concluded that the boroughs planted by Ethelfleda and Edward were organised on a system of military defence, whereby the magnates in the country were bound to keep houses in the towns.[86] CYRICBYRIG.--About this place we adopt the conjecture of Dugdale, who identified it with Monk's Kirby in Warwickshire, not far from the borders of Leicestershire, and therefore on the edge of Ethelfleda's dominions. It lies close to the Foss Way, and about three miles from Watling Street; like Eddisbury, it is near the junction of two Roman roads. There are remains of banks and ditches below the church. Dugdale says "there are certain apparent tokens that the Romans had some station here; for by digging the ground near the church, there have been discovered foundations of old walls and Roman bricks."[87] Possibly Ethelfleda restored a Roman castrum here. At any rate, it seems a much more likely site than Chirbury in Shropshire, which is commonly proposed, but which does not lie on any Roman road, and is not on Ethelfleda's line of advance; nor are there any earthworks there. WEARDBYRIG has not been identified. Wednesbury was stated by Camden to be the place,[88] and but for the impossibility of the etymology, the situation would suit well enough. Weardbyrig must have been an important place, for it had a mint.[89] Warburton, on the Mersey, has been gravely suggested, but is impossible, as it takes its name from St Werburgh.
