Montfichet’s Tower, which is also known as Montfichet Castle, was one of a small number of fortifications located within the perimeter of London’s Town Walls. The tower overlooked a fording point over the River Fleet and remained in use until 1275 after which it was sold and demolished to enable the construction of a new Dominican Priory. Nothing of the castle is visible today.



Montfichet's Castle was built on Ludgate Hill inside the perimeter of the Roman London town wall. Situated adjacent to the medieval crossing point over the River Fleet, overlooking what is now Fleet Street, it was first referred to in a document dated 1130 although it is likely the structure was built in the years following the Norman Conquest. It took its name from its owners, the Montfichet family.


Little is now known about the structure although it is believed to have consisted of a tower (the site is normally referred to as Montfichet Tower) which, based on archaeological investigations in the late twentieth century, seems to have been surrounded by a defensive ditch plus a supporting bailey. It is probable the defences on the western side abutted the Roman Town walls.


The castle was strengthened in 1173 when the then owner, Gilbert de Montfitchet, joined the rebellion of Henry the Young King against his father. He retained his estates after the defeat of that uprising but in 1212 his grandson, Richard, rebelled against King John. Like nearby Baynard's Castle, it was destroyed by Royalist forces along with a number of other rebel owned fortifications including Richard's Mountfitchet Castle in Essex. Richard does not seem to have been deterred in his rebellion - he continued to support the Barons’ cause including compelling John to seal Magna Carta in 1215 and was one of the twenty-five Barons tasked with enforcement of the charter. Richard made peace with the Royal family after the death of King John and rebuilt his London castle shortly after.


Richard never married and the Montfitchet family died out with him in 1258. Like nearby Baynard's Castle, the site was purchased by the church in 1275 to form part of the new Dominican Priory that became known as Blackfriars. All traces of the castle have now gone.
