Quarrendon's site is now a large area of fields and riverside meadows which provide green space between modern housing developments on the outskirts of the town of Aylesbury. Visible in these fields and meadows are the remains of a medieval village, a church, a manor house and its moat and a Tudor water garden. These historic features are now nationally-protected as a Scheduled Monument. The area also has wildlife value with a mixture of habitats and the River Thame forming the southern boundary of the site.
The layout of the village of Quarrendon in the late middle ages is preserved among the earthworks which can be seen in the area today. At this time the village consisted of farmsteads which were clustered around irregularly shaped greens, linked to each other, to their fields and to Aylesbury by sunken roadways. This village had developed over a long period, centuries, during which time the layout and social structure may have changed. The earthworks which form the visible remains are important but below these there are probably more remnants and artefacts which could be excavated by archaeologists in the future. There are also areas which were significant to the village which are outside the boundaries of the scheduled monument, these areas should also be under appropriate management. An example is that of a field containing ridge-and-furrow, which is an indicator of a medieval open field system of farming. situated between the scheduled monument and Quarrendon House Farm. There are two deserted village sites which are considered to both belong a single medieval settlement which shifted, during the medieval period, from a less suitable location. The smaller of the two sites is west of the ruined building of Church Farm and consists of some platforms used to build houses on and a trackway which runs from east to west across the pasture. On the western edge of the pasture is a considerable flat area crossed by a wide street, this may represent pens and a drove way. The second village site is to the east of the smaller site and it is though that the villagers of the original settlement shifted to this site. The village was probably abandoned around 1485. The layout of streets and houses is clearly represented by the visible earthworks and show a village which covers with the streets and crofts radiating out from a pond with a mill and a sunken main street, which runs westwards from the village up the hill to the manor. The ruins of a small 13th century church, St Peters Chapel can also be made out
