The Castle Grounds.
Around the castle, as would be expected, is a complex series of earthworks. These would have been developed, as the moat was constructed, from the excavated soil. However, it was discovered, by the Royal Commission on the Historical Monuments of England (RCHME) that these earthworks were also, once, landscaped gardens with water features, designed to enhance the castle. However, the only water feature surviving today is the moat.
The moat is not rectangular, as would, perhaps, be expected and the castle is not central to it, but slightly to the south of the moat's centre. The broader, more wedge shaped, northern end of the moat reflects the northern edge of a string of ponds to the north-west and east. The outlines of these ponds can still just be made out, but have been seriously damaged by drainage and dumping.
The moat is kept full by a series of springs, several of which rise from within the moat itself. To the north-west there are traces of a pair of tapering ponds that were once retained by a dam across which the present path runs and from where the original bridge to the octagon ran. It was from these ponds that further springs derived and the moat was supplied with water from the dam.
Immediately to the east of the north-east corner of the moat are traces of a further pond. A large dam would have separated this pond from the moat and the pond was so large it was known as the 'Little Moat' on some nineteenth century maps.
To the south and south-west of the castle are further complex earthwork features. One, a large rectangular hollow (located between the car park and the castle) known as the 'Tiltyard' once had plans to be drained and turned into a village cricket pitch, but was unsuccessful. The 'Tiltyard' originally held water and was fed by the leat from 'Dalyngrigge's Bay'. It would have been the header pond for Dalyngrigge's mill, that was situated nearby. In the north-east corner of the 'Tityard' you will still be able to see a World War II pillbox, built in 1940.
