closed to further burials when it ran out of available space in 1884. To mark his inheritance of the title in 1349, the 3rd Baron, Sir John de Willoughby, built a private chapel on his estate. Dedicated to the Holy Trinity, it was endowed with collegiate status, with a master and up to twelve priests. When the head of the family founded the King Edward VI Grammar School in 1550, the school initially had no school building. The twenty or so children were taught in the Eresby chapel building for the next sixty years. The Willoughby family provided a school house in 1611, by converting an agricultural building on the edge of the estate. In 1839 the school house of 1611 was replaced by a new school building that was constructed on its current site, with funds provided by the 25th Baron, who was the first Earl of Ancaster. The site of the Manor House was partially excavated in the mid 20th century by archaeologist and folklorist Ethel Rudkin. Bolingbroke Castle Bolingbroke Castle was built in the nearby parish of Bolingbroke after 1220 by Ranulph de Blondeville, Earl of Chester and Earl of Lincoln. Henry de Bolingbroke, later to become King Henry IV at the age of thirty-two, was born at Bolingbroke Castle in 1366. The castle was much damaged during the English Civil War and, after the nearby Battle of Winceby in October 1643, only the lower sections of the outer walls remained. The last standing section of the castle, the gatehouse, collapsed in 1815. Bolingbroke's original walls, also constructed of Spilsby greenstone, were in an irregular hexagon, with round towers on five of the corners. The gatehouse consists of two towers built about 3 yards apart. Leading to a portcullis further inside was a drawbridge that spanned the moat. The moat encircled an area about 87 yards in diameter. The six walls were 6½ feet wide and varied in length from 16 to long. There was a small priest door in the rear wall just above the moat water line. The castle garrison was supported and supplied by an important market village outside the castle walls. It included several small farms, a friary and salmon lakes, two mills, and the chantry church of St. Peter & St. Paul.
