The remains of the church at Midley are situated on a slight rise between Lydd and Old Romney. Only the west gable and fragments of the north and south walls remain upstanding, rising to a maximum height of 8 metres. The walls are made of unusual buff-coloured bricks. Although deteriorated, the window openings and doorway survive in sufficient detail to suggest a date in the later 15th century for the building of this part of the church. The complete ground-plan of this structure is assumed to have survived unaltered since the decay of the church since before 1573. Midley church (formerly "Midelea"), however, is mentioned in Domesday and at least one phase of church is presumed to underlie the present ruined building, signified by the distinct mound some 20m by 15m on which the upstanding remains are situated. The underlying church is likely to date from the 12th/13th century, and is contemporary with a neighbouring deserted medieval village (now destroyed). Around the ruins, especially on the west side, fragments of human bone visible on the surface indicate the location of a graveyard belonging to the church. The upstanding walls are listed grade II (Vol. 437, 9/99). The remains of the later 15th century church at Midley survive only partially but to an impressive height of 8 metres at the west end. The upstanding walls and ground-plan of this church are of great architectural and historical importance because the church demonstrates a very rare and early use of brick for building in the region. The site is lent additional importance by the high archaeological potential of the land around the surviving remains, both for the earlier church buildings considered to survive as foundations below the present structure (Domesday Book refers to a church at Midelea) and for its adjoining graveyard in which bone is well preserved. From these archaeological contexts can be expected evidence of the disastrous floods in ca. 1287 (eg. changes in the death rate, evidence of depopulation, flood damage to the church itself). These were the same floods in which Old Winchelsea perished and which precipitated dramatic changes in the development of the region for which little evidence survives, relevant contexts having been either submerged by the sea or altered in more recent times.
