(339) Moat, remains of, in Chesterton, N. of Scotland
Road, at the centre of the circle described by Eastfield (O.S.
25 ins. XL 15; N.G. 465603), is on flat ground approx. 27 ft.
above O.D. It was square on plan, enclosing an island 37 yds.
wide and level with the ground outside. The ditch survives
along the S.E. side; it is dry, 24 ft. wide and 3 ft. deep. The
cutting elsewhere is filled in but faint traces of the scarp of
the island are discernible. Condition, poor.
(340) 'Mount Ararat', raised enclosure, in Chesterton, on
the N. side of Water Street, 250 yds. W.S.W. of the levelcrossing (O.S. 25 ins. XL 15; N.G. 472602), stands on flattish
ground under 20 ft. above O.D. It is an irregular rhomboid in
shape covering approx. 1 acre, raised from 1 ft. to 3½ ft. above
the surrounding ground, scarped on the W., N. and E. sides,
and with a low bank on the S. This last has a deep drain
outside continuing E. some 40 yds. beyond the enclosure
before turning N. at the field angle; from the angle a causeway
1½ ft. high leads back into the S.E. corner of the enclosure.
The ditch continues N. and may have turned W. to form a
N. boundary where is an apparently modern drainage channel.
The enclosure is only some 60 yds. from the river and may
have provided a cattle-fold in time of flood. Condition, much
disturbed, with gravel pit on the N.
(341) Worts' Causeway, remains of raised roadway
leading from Cambridge to the Gog Magog Hills S.E. of the
city by way of Red Cross. It coincides in part with a more
ancient way (see Roman Roads, Monument (10c)).
William Worts, dying in 1709, left £1,500 for building a
causeway from Emmanuel College to the Gog Magogs and
an annual sum for upkeep (C. H. Cooper, Annals of Cambridge
IV, 86). The convenience of the causeway is referred to in
Cantabrigia Depicta (1763) 'gentlemen ride out [the 4 miles
to the Hills] clean in the depths of winter'.
The Causeway is visible leading E. by S. from the Hills
Road at Red Cross for nearly 1½ m., in part along the city
boundary; it then passes out of the city and continues as an
unnamed country road in Fulbourn parish. The embankment
is about 17 ft. wide and stands 2 ft. to 3 ft. high.
