The oldest land based fort of the Defence Line. The bombproof buildings were built between 1884 and 1887 of both old style brick and modern concrete. The masonry is in perfect condition and still looks as if it was finished last year.
It could shelter 284 men and there was room for ammunition.
It is now owned by the city of Abcoude and because it was a military object it could not be visited and has a wide range of animals and plants, some of which are rare.
The site is of outstanding universal value as it is an exceptional example of an extensive integrated defence system of the modern period which has survived intact and well conserved since it was created in the later 19th century.
