English: Kings Langley: Site of the former Royal Palace The former Royal Palace at Kings Langley was built under the supervision of Eleanor of Castile (1241 - 1290), wife of King Edward I. It appears to have been started around 1276 and to have been completed by 1299. This is how the village of Langley got its epithet Kings. Edmund de Langley, the first Duke of York and fifth son of King Edward III, was born here in 1341. Around 1349, during the outbreak of plague, known as the Black Death, King Edward III used the Royal Palace as his seat of government away from London. The Palace seems to have fallen into disuse during the Wars of the Roses, and was demolished around 1469. Apart from occasional underground finds during construction works for the nearby 1338266 nothing remains of the former structure. The Ordnance Survey 1:10,000 scale map shows the centre of the site to be in the rear gardens of the houses in the photograph, probably the second house from the right being where the actual symbol is. This photograph was taken from the footpath leading south.
