Construction of Rochester Castle

The site has had Roman and Saxon fortifications for hundreds of years until the Norman Conquest. Odo built the first Norman fortifications on the site, which, updated many times over the following fifty years to a stone curtain wall 'Bailey' and the stone keep. The builders of the Keep used part of the original wall built by the Romans as the foundations for the new stone building.

The tower-keep at Rochester was begun sometime around 1087 by Bishop Gundulph (William the Conquerors personal architect) and fully completed by 1126 by William de Corbeil, the Archbishop of Canterbury with the permission of Henry I (King 1100-1135 the fourth son of William the Conqueror). The Keep is the tallest keep in Britain at 125 feet, also the third largest in area after the Tower of London and Colchester.

The Keep has withstood three hugely damaging sieges. The most famous and the most damaging being the bloody and violent siege of King John in 1215. King John laid siege to a small group of rebels led by Barons. The siege lasted for three months and many of the tactics used form a huge part of our current understanding of siege warfare with castles. The siege proved to be the end for large Keeps. The large keeps were vulnerable when undermining used as a method of breaching the walls. This siege also led to repairs, which saw one use of a round turret instead of the standard square design. Showing the evolution of understanding of how to improve a castles resistance to siege weapons.

At 125 feet tall, the keep at Rochester remains the tallest castle keep in Britain. In addition, some rare maps indicate that later repairs may have given the keep turrets roof designs similar to the Tower of London. However, evidence for this is very scarce and limited.

 


 
History of the City of Rochester

Great website to learn about the history of our famous city.

1965 -

In 1965 the castle was felt to be at serious risk and was taken under the care of the Government (Ministry of Public Buildings & Works). The departmental successor 'English Heritage' is now responsible for our castle. Although day-to-day management of the keep is with Medway Council English Heritage, remain in control as Deed & Title owners of this scheduled ancient monument.

Over the decades since 1965, many discussions have invoked interesting debate about restoring the roof and floors.

Many believe the only way to safe guard this; probably the greatest keep in England is to roof it. The walls are currently open to the weather and elements on both sides. This is directly in contrast to the design and structural ability of the building.

A romantic attachment to the Keep as a ruin is largely responsible for her current predicament.

In March 2010, part of the Bailey Curtain supporting wall collapsed after sustained heavy rain. The long overdue study (yet still unfunded and still not contracted to commence) is still required. Yet not one person could say with any confidence that the castle could not or would not suffer a further collapse of other parts after further poor weather. This is clearly unacceptable for a Keep of this importance to degrade to such a degree.

Robin Kent Architectural, Conservation Company who completed a detailed study and preliminary work on the castle concluded

"The poor state of the walls is an ongoing problem that urgently requires resolution. Severe winter conditions are likely to cause accelerated deterioration: while the monument lacks its roof, the walls are receiving double the amount of weather they were designed for."

1900-1965

The castle keep underwent repairs during this change, sadly, the concrete used was the wrong type and it is partially due to these repairs that the keep is deteriorating much faster. In fact, the cement added in the 1950's has caused water to pool inside large voids in the walls. This presents the immediate threat to the castle as one severe winter could spell the end of the Keep, as we know it.

1600-1800

Rochester Castle has stood as a ruin since a possible fire around 1600, although there is a surprising lack of fire damage to the keep visible today, including a lack of burnt embers in the supports holes for the floors. In addition, it seems if such a fire did occur it would have been visible for miles but there is no clear mention of such a fire in historical records.

Large sections of the bailey curtain wall have been lost over the last four centuries. Some stones it is considered were moved and used in the construction of Upnor Castle. Since 1600 those entrusted with its care sadly used it to further their own ends. Twice the castle faced attempted demolition. Twice the companies charged with the task conceded defeat.

A huge scar on the East Keep wall is the result of an attempt to blast the Keep with dynamite. Once ignored as being too weak to withstand modern explosives this scar is testimonial to the Norman stonemasons and skilled workmanship of the 11th Century.

There were a few attempts made post the demolitions to try to restore the castle. The wellhead visible when you enter the keep is a later addition. Sadly, many of the attempts to restore the keep actually did greater damage and for some reason the gate to the castle was demolished to improve access. Some of this still exists but is not visible. As you enter the Bailey gardens through the Boley Hill entrance, you are walking over the foundations to the gatehouse.

In the 19th Century, the local Council purchased the Castle and the grounds converted into a park. The pictures, taken at the time show an ornate garden popular with young couples and families.

Recently discovered pictures from Medway Archives clearly show part of a Bailey Cross wall still standing with arches, whether this was an original feature or not is subject to debate. Probably demolished around the time the Gatehouse lost to improve access to the new Victorian gardens.

The sad loss of such a structure so recently underlines the abuse the awesome castle has had to endure at the hands of her so-called protectors.

Parts of the Bailey Curtain Wall were also lost around this Victorian period, the esplanade and 'Lovers Arches' constructed with the gardens that now wind down towards the River Medway River.


King John's Siege of Rochester Castle

During this siege the castle keep was breached by the under mining and then intense heat from burning pigs fat placed in the mine to burn the supports under the tower.
The evidence of the breach is still visible today by the reconstruction that gave the Keep its new round turret.

 
Lady Blanche de Warenne

The castle is said to be haunted by Lady Blanche De Warenne, - a woman all in white, said to be Lady Blanche de Warenne, who was killed by an arrow through her heart during the fighting. Her appearance has been documented many times, staggering along the battlements with the arrow still protruding from her chest. However, there is also a more recent ghost - that of Charles Dickens who is said to haunt the moat on Christmas Eve.

There are also rumours of a Drummer Boy that can be heard beating his drum from time to time at certain hours throughout the night... from the website:
