On the site of an earlier timber fort, destroyed by order of Henry II, Roger Bigod (2nd Earl of Norfolk) succeeded his Grandfather by building a second castle at Framlingham. Work commenced in 1177 and took almost forty years to complete. Although a traditional Keep was not built within the castle, Framlingham does have a very impressive series of 13 towers set along the length of a magnificent curtain wall that looks today almost as it would have 800 years ago. However, this external 'shell', showing the walls standing nearly full height, and all the towers (complete with their tudor chimneys) surviving, is very deceptive. Inside, almost nothing remains of the original Framlingham Castle, save for a few traces of fireplaces, and the 17th century almshouse building.

Framlingham Castle has an interesting history as a result of many different ownerships and has, during its life, been a fortress, a prison, a poor house and a school. The Bigod family rebelled against Royal authority, and Framlingham castle was first taken by King John in the early 13th century. During the reign of King Edward I Frmalingham Castle became the property of the Mowbray family, and later passed through Ann Mowbray to the Howard family who were responsible for extensive repairs to the castle.

Despite being one of a number of properties owned by the new Earls of Norfolk, because Framlingham Castle was less elaborate as a residence, it was little used. Therefore, during the 17th century the castle was bequeathed to Pembroke College with the condition that a poor house be constructed. It was at this time that the majority of Framlingham Castle's original buildings were purposely demolished. The Great Hall, built by the Bigod family along the western curtain wall, was incorporated into the structure of the poor house, and the three small windows at low level date from that original Norman hall.

Framlingham Castle presents a picture of strength, standing proudly against a background of gentle countryside, and must have been an idyllic place for Mary I to while away those summer days waiting for news of whether she was to become the next Queen. Although exploration is limited, there is a continuous wall walk which can be exhilarating on a bright, but fresh day in Suffolk.
