Some buildings in Tudor City have vaguely medieval names ‒ The Cloister, The Hermitage, The Manor ‒ in keeping with the colony's Tudor character. Then there are the 3-H's, which are named after specific English country estates. Downton Abbey, eat your heart out: here are the other 3-H's.
Haddon Hall Hardwicke Hall Hatfield House
Above, Tudor City's 3-H's in 1929. And below, the three country houses they were named after. We can definitely see some resemblances.
Haddon Hall, Derbyshire
Begun around 1100, Haddon Hall underwent various additions and alterations over the next 500 years, and today is considered one of Britain's finest medieval homes. It's currently occupied by Lord Edward Manners ‒ it's been in his family since 1567 ‒ and is open for tours, details here.
Hardwick Hall, Derbyshire
Constructed in 1570 by Robert Smythson in the Renaissance style, Hardwick Hall is particularly notable for its abundance of windows. Currently owned by the National Trust, Britain's equivalent of America's National Register of Historic Places. Open for tours, details here.
Hatfield House, Hertfordshire
Built in 1611, Hatfield House is a prime example of Jacobean architecture. Remarkably, it has been owned by the same family throughout its long life, and is currently occupied by Robert Gascoyne-Cecil, the 7th Marquess of Salisbury. It also offers tours, details here.
