I visited Holdenby some years ago but have no record of the details. The recent visit was in April 2019. The core of the house is the remains of the kitchen wing of a vast Elizabethan palace, restored and extended in the Victorian era. Two unusual arches, once part of an entrance court, stand in the grounds. The house is open to the public on only a few days of the year. The tour includes the entrance hall, the boudoir (sic) the piano collection room which contains a number of antique pianos and other instruments, the Pytchley Room (with sporting pictures), the Ballroom, the Inner Hall, the Library and the Dining Room.
The grounds include smaller areas of formal garden, a kitchen garden, a primitive-looking replica wattle & daub cottage and a falconry.
Below the house is an interesting church, now in the care of a preservation trust.
