 A set of grand castellated Tudor-style gates survived at the Rickmansworth Road entrance to the park for several decades, but were finally demolished in 1970 by Watford Borough Council to allow road widening along the A412 road.As with many British country houses, when the Cassiobury estate was sold off in 1923, museums in America and elsewhere bought the fixtures and much of the art collection.As a result of the of the Earl's assets, valuable remnants of Cassiobury House can now be seen in various museum collections around the world.
