Awful! Started in a vape shop and the 1850s buildings are gone. I can only hope that starts to allow firefighters to get it under control.

John Lewis Roget's pencil sketch of a two-wheel hand truck, flowers and adult and child passengers in period hats, suits and dresses at Deal and Canterbury railway stations.

John Lewis Roget's pencil sketch of a two-wheel hand truck, flowers and adult and child passengers in period hats, suits and dresses at Deal and Canterbury railway stations.

Welcome aboard today's #commute with John Lewis Roget (1828–1908), calling at #Deal, #Dover, #Kearsney, #Canterbury and #Faversham.

Roget took every opportunity to illustrate the places he visited, including the railway station.

For Β£35k, which is zippity nada in the scheme of even impoverished council funding, just going to show that it's not actually about the money in any case. Vandals.

Over 100 works of art being put up for auction by (cash strapped) Reform-run Kent County Council.

Kent Greens: "While the total financial value of the art is only around Β£35k, the historic and social value of the art, most of which depicts Kent, is far higher."

As @vrubinobs.bsky.social gets going with its survey of the sky, nice to be reminded of a Fred Hoyle quote: β€˜a large telescope is a good example of the things which our civilisation does well’.

My photo shows the ruin of an eight-sided Roman brick lighthouse with four stepped levels. There is a central arched opening (doorway) at ground level. On the upper three levels, in line with the doorway, there are narrow rectangular window openings. The lighthouse stands 15.8 metres high and is 12.2 metres wide at the base. Roman fabric survives to a height of 12.5 m. The brickwork of the uppermost level was reconstructed for use as a church bell tower for the adjacent Anglo-Saxon church of St Mary in Castro, which can be glimpsed on the right-hand side of my photo. The lighthouse is dated circa 1st century to early- 2nd century AD. It was one of a pair originally built on each side of the Roman port of Dubris (Dover). The other does not survive. This lighthouse stands within the grounds of Dover Castle.

The Roman Pharos (lighthouse) at Dover, still standing after almost 2,000 years! 🀩

It is the tallest surviving Roman structure in Britain, and one of only three surviving lighthouses from the former Roman Empire! Dated 1st-2nd century AD.
