It has large areas of ancient woodland, especially oaks, and flowers include lily of the valley, which is rare in London. Ponds have London's largest population of protected great crested newts. Much of it is undisturbed grassland,[3] and it also includes a working farm.[5]
The main entrance is in Old Perry Street. The entrance piers still exist.[6]
Also a West Lodge to the estate still exists, also on Old Perry Street.[7]
The London Loop passes through it from Sidcup By-Pass Road near its junction with Perry Street to St Paul's Cray Road.
The manor is first recorded in the thirteenth century, when it was held by the de Scathebury family.[8] In 1424 it was purchased by Thomas Walsingham, a wealthy wine and cloth merchant in the City of London who served as a Member of Parliament in 1410 and 1413.[9] The manor was the seat of his descendants until about 1655. These included Christopher Marlowe's patron, Sir Thomas Walsingham; in fact Marlowe is known to have been staying at Scadbury Manor just before his violent death in 1593. Queen Elizabeth I's spymaster, Francis Walsingham, was born there.
