whole area of the castle was enclosed by its original founder, and is not later than the middle of the twelfth century, the detached fragments of walls and buildings being in substance of the same date with the keep. The castle is in St. Mary's parish, bordered on the north-east by Trinity, and on the east by the extra-parochial plot, the origin of which is not known. Probably the enceinte took in the whole of the residence of the royal Saxon owners.
Those who have supposed that the enceinte of the castle extended to the present High Street, have regarded the two well-known crypts remaining there as proofs of this extent. One of these, on the south side, the writer has not been able to visit; but the other, exactly opposite the former, and about 160 yards from the keep, he has examined, and it is said that the two are of the same age and dimensions, and very nearly alike.
The north crypt, beneath the Angel Hotel, is a rectangular chamber, 31 ft. north and south, by 19 ft. east and west, and divided into two aisles and six bays, by two central piers. The piers are plain cylinders, 18 in. diameter, and 5 ft. 6 in. high. The bases are now concealed; the piers are with- out caps, and quite plain. The roof is vaulted, and 10 ft. 3 in. from the floor to the cornice, groined and ribbed. The arches are drop, and pointed, the ribs chamfered, and springing from carved corbels in the wall. At the south end of each aisle is a window recess, converging and rising to a loop at the street level. The entrance is by a narrow drop-arched door, opening from a rising passage, vaulted, with hanging ribs. This opens into a small chamber, north of, and 4 or 5 ft. above the vault, whence another narrow door probably led up to the ground level. The date of the crypt seems to be of the thirteenth century, and it is quite clear that it never was prolonged southwards towards the other crypt, and was always and only lighted, as now, from the street level. In all probability this was the cellar of some considerable hostel, situate, as now, in the High Street, which, in the twelfth and thirteenth centuries, as now, w as probably the main thoroughfare of the town.
In the immediate neighbourhood of the castle, and, indeed, running under the southern edge of its enceinte, are the celebrated caverns, which have recently been explored,
