Baston is a village and parish on the edge of The Fens and in the administrative district of South Kesteven, Lincolnshire, England. The 2011 census reported the parish had 1,469 people in 555 households.
Like most fen-edge parishes, it was laid out more than a thousand years ago, in an elongated form, to afford the produce from a variety of habitats for the villagers. The village itself lies along the road between King Street, a road built in the second century, and Baston Fen which is on the margin of the much bigger Deeping Fen. Until the nineteenth century, the heart of Deeping Fen was a common fen on which all the surrounding villages had rights of turbary, fowling and pasture.
A significant Roman feature of Baston is the Roman road leading across the fen towards Spalding. Part of the modern fen road follows it.
At the end of the village, near King Street, was an Anglian cemetery which was in use up to about the year 500. This coincides approximately with the date of the beginning of King Arthur's exploits, as reported by the Historia Brittonum, when Arthur fought his first battle at the mouth of the River Glen and stopped the spread of Anglo-Saxon settlement for fifty years. The Anglo-Saxon cemetery, of funerary urns, was found by Rev. Edward Trollope in 1851. He found around 10 burials in 1863 and traces of another 16 were found in 1963
Like most places in Europe, Baston suffered from the plague. Some Baston plague victims are shown in burial lists. A possible plague burial was uncovered during the building of a corn dryer.
