House & Family History: Lord Byron spent his infamous 1815 honeymoon (he referred to it as his "treaclemoon") at Halnaby Hall, the ancestral home of his wife, Anne Isabella Noel Milbanke. The couple separated in 1816 and the physical remnants of their marriage have been collected ever since. The Keats-Shelley House in Rome has on display a piece of red damask from the Byrons' honeymoon bed at Halnaby; on December 13, 2018 another piece of fabric from the bed was sold at auction by Dominic Winter Auctions for £1,600, against an estimate of £2,000–£3,000. Halnaby was noted for its exceptional Rococo plasterwork, particularly in the richly detailed dining room. Halanby Hall appeared on the cover of the catalog for the seminal exhibition "The Destruction of the Country House," held at the Victoria & Albert Museum in 1974.

Collections: A carved and gilded wood Rococo mirror in the Chinoiserie style that once hung in the drawing room at Halnaby is today in the collection of the Victoria & Albert Museum, London (see "Images" section). The mirror, which was probably made between 1750 and 1760, may have been copied from a design by Thomas Johnson.

Garden & Outbuildings: In the mid-19th century the Halnaby Estate stood at 15,000 acres. The stables have been converted into a B&B.
