Bletsoe Castle was a late medieval fortified manor house in the village Bletsoe,
Bedfordshire.
Bletsoe Castle was created by John Pateshull, who received a license to crenellate
an existing manor house on the east side of Blestoe in 1327. Pateshull had owned
the manor of Blestoe since 1313, but in 1324 he inherited additional lands,
allowing him to acquire permission to crenellate the property.
In the late 16th or early 17th century, a new building was erected around the
castle, quadrangular in design with three or four storeys and gable windows.
Much of this later building was pulled down, leaving a much smaller building,
still incorporating parts of the older castle, within the older medieval earthworks.
Today the castle is a scheduled monument and a Grade 2* listed building. The
medieval moat has a diameter of 130 m, is on average 18 m wide and 2.4 m deep
and is water-filled in parts; the south side has been destroyed by the construction
of agricultural buildings over it.
