Poulton Stocks ....
shhhh - Poulton stocks are known to be mediaeval or medieval ( depending which version and spelling you think is correct! ) and they’re, apparently, flanked by the posts in question. Unfortunately, however, these pillars are not the originals. The September 1992 edition of Lancashire Life reliably informs us that: “In the days when double-deck buses had to make a tight turn, these were shattered several times and had to be replaced by weathered stone posts salvaged from local farms.” Images below taken by myself and own collection.
