Fotheringhay Castle, also known as Fotheringay Castle, was a High Middle Age Norman Motte-and-bailey castle in the village of Fotheringhay to the north of the market town of Oundle, Northamptonshire, England (). It was probably founded around 1100 by Simon de Senlis, Earl of Northampton. In 1113, possession passed to Prince David of Scotland when he married Simon's widow. The castle then descended with the Scottish princes until the early 13th century, when it was confiscated by King John of England. By 1220, Fotheringhay Castle was controlled by Ranulf de Blondeville, 6th Earl of Chester. In January the following year, it was briefly captured by William II de Forz, 3rd Earl of Albemarle, in his rebellion against King Henry III. Forz abandoned the castle, Henry III took it under his control, and Fotheringhay remained in royal hands until the reign of Edward II. It was a favoured residence of the Dukes of York, and King Richard III was born there in 1452. It was also the final place of imprisonment of Mary, Queen of Scots, who was tried and executed in the castle in 1587. The castle was dismantled in the 1630s and most of the masonry was removed, leaving only the earthworks. The site is protected as a Scheduled Monument and is open to the public. William the Conqueror granted the area to Judith of Lens, wife of Waltheof, Earl of Northumbria. Their eldest daughter, Maud, inherited the lordship of Fotheringhay. Around 1090, she married Simon de Senlis who was made Earl of Huntingdon, and about 1100 he founded Fotheringhay Castle, on the northern side of the River Nene. Simon had died by 1113 when King Henry I of England arranged for Maud to marry Prince David of Scotland. Through this marriage, David, who later became King of Scotland, acquired Fotheringhay Castle, as well as other properties in Huntingdonshire. Possession of the castle descended through the Scottish princes until the 13th century. Shortly after King John was excommunicated, he demanded his barons send him hostages to ensure their loyalty.
