Seaton Delaval Hall (the Gay Delavals)

Vanbrugh's baroque masterpiece was home to the 'Gay Delavals' — Georgian England's most theatrical rakes, whose house parties featured mechanical beds that dropped guests through the floor mid-assignation, walls that slid away to expose bedrooms, and Sir Francis Delaval's celebrated seductions staged like productions.

The story

Fifteen hundred pounds — a small fortune — was what Sir Francis Blake Delaval spent hiring Drury Lane for one night in 1751, so he and his siblings could star in their own Othello. The Commons adjourned early to attend; the Prince of Wales came; Horace Walpole noted the footmen's gallery "strung with blue ribands." That was the Gay Delavals — gay meaning merry, extravagant and scandalous — the family who made Seaton Delaval Hall the loudest house in Georgian Northumberland.

Vanbrugh designed the Baroque masterpiece between 1718 and 1728 for Admiral George Delaval. Neither architect nor admiral lived to see it finished. It was the next generation who spent liberally, gambled, staged plays and pantomimes at home, and acquired a reputation for tormenting house guests. The famous pranks — beds winched up on pulleys and dropped into cold-water tanks, walls that slid back to expose sleepers, rooms turned upside down, geese smuggled into the bedclothes — should be handled with care. The National Trust confirms the pranking reputation is genuine but notes the elaborate mechanical versions are largely Victorian embroidery, much of it from the 1880s. The solid fact is the theatrical mania: lessons from professional actors, home performances, and that ruinous night at Drury Lane.

Sir Francis (1727–1771) — described in the Oxford Dictionary of National Biography as a rake — kept a mistress, Betty Roach, and left at least five illegitimate children. In 1750 his family married him off to a wealthy elderly widow to clear his debts; he spent her money on his mistress. He died at forty-four, alcoholic and largely alone.

Fire gutted the central block in 1822, so fiercely that glass melted. It has stood as a roofless shell ever since. The Trust took it on in 2009 and wisely left the shell as a shell.

Starlight Castle, built for a bet

Sir Francis's brother John raised a small folly, Starlight Castle, overlooking Holywell Dene — reputedly thrown up in a single day to win a wager. Little survives but the name and the story, which is fitting: the Delavals specialised in enormous effort expended on things that did not, strictly, need doing.

A third foot in the family portrait

During conservation, curators found that a painting of the Delaval sisters had been altered — one girl appears to have three feet, and the canvas bears what looks like damage from a champagne cork. Even the family's art records the wear and tear of relentless partying.

The bats moved in

After the 1822 fire the gutted central hall was left open to the elements, and it became the largest maternity roost of common pipistrelle bats in the region. The grandest room the Delavals ever built now belongs entirely to the wildlife.
