Rooves for hooves

The roof at the indoor riding school at Bolsover Castle.

If you have never been to Bolsover, you must go. It is an incredible creation, a palace of amusements built for pleasure and to demonstrate power by William Cavendish, a man of huge personal fortune and great political achievements under the Stuarts - facts which are not unrelated, since Charles I favoured generals who could afford to pay their own armies. I rather like this CV-style list of titles from Wiki:

Mr. William Cavendish (1592/1593-1610)
Sir William Cavendish, KB (1610-1620)
The Rt. Hon. The Viscount Mansfield, KB (1620-1628)
The Rt. Hon. The Earl of Newcastle-upon-Tyne, KB (1628-1639)
The Rt. Hon. The Earl of Newcastle-upon-Tyne, KB, PC (1639-1643)
The Most Hon. The Marquess of Newcastle-upon-Tyne, KB, PC (1643-1650)
The Most Hon. The Marquess of Newcastle-upon-Tyne, KG, KB, PC (1650-1665)
His Grace The Duke of Newcastle-upon-Tyne, KG, KB, PC (1665-1676)

He had 10 children by his first wife, which seems to have led to her demise, and married Margaret Lucas, who was 31 years his junior and had been a maid of honour to Henrietta-Maria, in Paris while they were both exiled during the Commonwealth.

Margaret Cavendish was known as 'Mad Madge of Newcastle' by the London wits because she wrote poetry, biography and, most shockingly, both natural philosophy and metaphysics. I'll save telling you about her philosophy for another time, but it is worth noting that she is still in print, though rather heavily edited and abridged.
