Thomas Wright was born in the little village of Byers Green, near Spennymoor, in 1711. He disappeared for the duration of his working, adult life, before returning to the area in his retirement, where he set about building the still-existing Westerton Tower. He died before it was completed, meaning that his planned observatory became little more than a folly adorning the Durham landscape.

Wright had his fingers in a lot of pies. He was schooled in Bishop Auckland, before being apprenticed to a clockmaker in the town. In his working life he began as a teacher of mathematics and navigation at his own school in Sunderland in the 1730s, before moving to London to work for several wealthy patrons. He dabbled in garden design, was a bit of an architect and designed scientific instruments – famously building a huge working model of the solar system (an orrery) for one of his clients. Indeed, Wright is best remembered as an astronomer.

Despite what you may have read elsewhere, it was Thomas Wright who first speculated that the Milky Way was most likely a flat disc of stars, and that the blurry blobs of light we see in the night sky (nebulae) are actually distant galaxies. These ideas are often attributed to the brilliant German philosopher, Immanuel Kant, but they first appeared in Wright’s An Original Theory or New Hypothesis of the Universe in 1750. He also helpfully (and correctly) postulated Earth and humankind’s relative insignificance in the ‘grand scheme of things’, and was the first man to coin the phrase ‘galaxy’ to describe a large group of stars.

Retirement sent him back to his homeland in Co.Durham, where he set about work on his pretty little observatory (though construction may have begun earlier in his lifetime). His death in 1786 preceded the tower’s completion, so his planned observatory rather unfairly became a mere folly. It has been used, periodically, as a reading room and more recently as council offices. A commemorative plaque was placed there by Durham University in 1950 to celebrate the 200^th anniversary of the publication of his famous treatise.

Sharp’s Folly (NU058009)

Sharp’s Folly, or Tower, is reckoned to be the oldest folly in Northumberland. It is situated near Whitton, a little to the south of Rothbury, and was built in the 1720s by Rev Dr Thomas Sharp, Rector of Rothbury during 1720-58.

When Sharp (the son of the Archbishop of York) moved to the locality he set up his household in Whitton Tower. He was something of an eccentric, for sure, but, taking pity on the unemployed men of his parish, he hit upon the idea of building the 30-odd foot high ashlar structure as a sort of job-creation scheme.

It wasn’t a folly in the purest sense, though, for the tower, after its construction, was thereafter used as an observatory for the reverend’s astronomical interests. You could see the sea from its summit, apparently, until the nearby trees grew to obscure the view.

The tower is privately owned so the visitor cannot climb its internal cantilevered stone staircase. However, as you can see from the picture, passing hikers can get close enough for a good gawp.

Ratcheugh Observatory (NU224146)

This curious construction sits upon Ratcheugh Crag, about 2 miles NE of Alnwick, in full view of the East Coast railway line. Commissioned by the 1st Duke of Northumberland, designed by the great Robert Adam and built by John Bell of Durham, its exact date of erection cannot be precisely pinned down – but was probably thrown up around 1770-80. It is what can only be described as a useful folly – if that isn’t a contradiction in terms – the first floor offering spectacular views of the coast and surrounding countryside.

This lofty site was a favourite picnic spot for the Duke and his Duchess, though some sources suggest the building was built in memory of the latter, who died in 1776 – which would be a shame, really, as I’m sure she’d have loved it. The structure has recently undergone repair, and is occasionally opened to the public.

The 2nd Duke later added a cottage for a keeper near the observatory (not in picture), to give the whole craggy prominence a rather eccentric look. Hereabouts, too, are to be found many Iron Age relics – and Ratcheugh Farm is a regular venue for the age-old pastime of point-to-point horseracing.

An odd and interesting place is Ratcheugh.
