Unable to answer "What kind of memorial is this?" for https://osm.org/node/2003145538 via StreetComplete 53.1:

This is a market cross. It's a historic site (see https://historicengland.org.uk/listing/the-list/list-entry/1155090?section=official-list-entry) and there is a plaque on it, but it's not really a sculpture.
