Since I moved near my family four months ago, my sister-in-law has read three Jane Austen novels – Pride and Prejudice, Sense and Sensibility, and Persuasion. She took a longer time warming up to Persuasion, but came around in the end, enjoying the experience.
As a Jane Austen devotee, I associate the seaside resort of Lyme Regis with Persuasion. Imagine my delight to find that the book Lyme Regis: A Retrospect had been digitized by the Internet Archive. I digitally “flipped” through the book and was delighted to view a number of illustrations of Lyme Regis in the era of Austen.

The fronticepiece of the aquatint of Lyme Regis by William Daniell, R.A. This aquatint first appeared in Daniell’s well-known Voyage round Great Britain, published in 1814. The Charmouth end of the lane, which once ran along the edge of the cliffs for the whole distance between Lyme and Charmouth is here shown.

This picture of the Cobb…is taken from the 1724 edition of Stukeley’s Itinerarium Curiosum. The original plate is subscribed ‘Lyme, 21 Aug. 1723.’
Excerpt from the book (it is copy right free!):
The Cobb shared in the changes that were taking place at Lyme after 1750. In 1756 the causeway from the western arm of the Cobb, which joins it to the land, was made. As a result of this construction, and the action of sea and tide, a huge bank of sand and shingle began to form in the angle between the new causeway and the mainland. For te first time in its history, Lyme was recovering some land from the sea…At what date exactly the houses were build is not certain, but they are on the drawing of the sea-front which is dated 1796, and they consequently were there when Jane Austen came to Lyme in 1804. In fact the one in which she placed the Harville family was build on this reclaimed land. Close to the warehouses on the Cobb had once been the ‘King’s Pipe,’ the place, that is to say, where spoilt contraband tobacco seized from smugglers by revenue officials was burnt. The palmy days of smuggling were during the period of high duties forced on us by the French Revolutionary Wars. Cargoes of contraband to the Dorset coast were generally run from the Channel Islands or the Northern Coast of France. If the George Inn still maintained its stables, its pack-horses may frequently have been employed at this time to carry smuggled goods inland. The smugglers were good employers and paid well.” – pp. 123-124

This Cruikshank-Marryat series shows the end of the Walk at Lyme Regis, so far as it went in 1819, i.e., to what is now No. 8 Marine Parade. – p.121.

The front of the Cliff House property…has suffered from continual falls…and the cottage where Jane Austen lodged (no longer standing alone) shows a greater variation from the perpendicular every year. – p. 122

Image of the Cobb in rough weather, copyright Tony Grant. Shipwrecks were not uncommon on Dorset’s shores. One can see the slanted top of the stone Cobb.

This view of the Bay of Lyme Regis is taken from the 1823 edition of Roberts’ History of Lyme Regis, Dorset.-p. 4.

This view of Lyme Regis is dated 1796. It was drawn by ‘J.Nixon, Esq.’ and engraved by John Walker…It was also utilized by W.G. Maton in his Guide to All the Watering and Sea-Side Bathing Places, a work which had a great vogue and was first published in 1803. Nixon was a clever amateur artist who exhibited at the Royal Academy. – p. 135.
Jane Austen makes Mary Musgrove, in Persuasion, bathe at Lyme in November. This is not a mistake; it is rather evidence that Miss Austen was a realist. The year was 1814, and in the autumn of 1814, Princess Charlotte of Wales was staying at Weymouth. Now The Western Flying Post for October, November, and December records that the Princess was bathing on some days of all three months until severe storms from and after December 12th brought the season to an end. Now what Princess Charlotte could do at Weymouth, the aristocratic Mary Musgrove both could and would do at Lme off the beach near Bay Cottage. (p. 140)
And so, in the course of the eighteenth century, Lyme Regis completely changed its character. From being a busy industrial and trading town it became a place of resort for visitors in search of health, amusement, and change. All early writers of Lyme as a seaside place insist on its superior ‘gentility’–a word once redounding in qualities to which all should aspire, but now greatly debased in meaning. ‘The residents are mostly persons of genteel, not large, fortune,’ says one. ‘At lyme,’ says another, ‘there arises no necessity for making any inconvenient sacrifices to the support of style or to the extravagance of outward show.’ -p.141.”
