As Grrr notes this is all occupied by a very smart stud farm but a footpath skirts the N side and views of the ramparts can be seen from here. Following the side road signposted to the church, much better views can be had of the S side.
Disabled: Parking might be possible at the stud farm (Please ask) and part of the N part is circled by a flat path with wide views to the N. To the S, parking is possible where the road branches to the church (is this area private?) but the road is steep.
