Yarmouth Castle was built around the time of Henry VIII in 1547,
located around 10 miles west of Newport. Its purpose was as a
defence against French attack. Built using stone from two
Monasteries, which had previously been dissolved by Henry, with a
doorway on the east wing. Accommodation blocks were positioned
along the southern wall, with the kitchen and service areas
situated at the arrow-head of the castle. Yarmouth Castle took a
different look to Henry VIII's usual structures of defence, which
were large circular forts with a keep at the centre. This castle,
however, is square, and runs in a line along the south and east
coast of the Solent, near to where his beloved flagship, the Mary
Rose, sank. From its original design, Yarmouth Castle has seen many
changes over the years, including angular buttresses built on the
west and north walls, and the filling in of the courtyard with
earth for gun platforms in the late sixteenth and early seventeenth
centuries. A second storey addition and a gabled roof put on to the
arrow-head bastion were also added at this time. The Master Gunners
House in the south-east corner was also enlarged, and in 1632, the
'Long Room' in the south-west corner was refurbished. During the
time when Richard Worsley was the Island's Captain, the original
three cannon and culverins, and twelve smaller guns were altered.
Several additions were made outside the Castle, with an eastern
defence wall constructed along the outer edge of the moat. This
took around fifty years to complete.
During the English Civil War, the Royalist gentry were under
Captain Barnaby Burley. However, the Castle was duped inadequate,
so he surrendered the castle to parliamentarians for reformation in
1660. It was then decided, after ten years, to remove the outer
earthworks, to fill in the moat, to build a large house and new
entrance in the south curtain wall. The next significant change in
the castle's appearance came in 1813. The platform's low wall was
altered, with gun rails laid for four naval guns. In 1869, the guns
were dismantled, and in 1875 the troops retired. Until 1901,
Yarmouth Castle was used as a coastguard signal station. Practical
use was made of the castle during the First and Second World Wars.
The English Heritage became Trustees of Yarmouth Castle in 1984,
making way for the public to access and admire one of the Isle of
Wight's most historic sites.
