An old post located on Tate's Avenue in Belfast (south side, under the bridge). The inscription at the top of the post reads "Water Boundary 1841". It is most probably a post indicating the limits of the newly-formed Belfast Water Commissioners (founded 1840). It is also likely that the post has been resited here from its original location - it appears to have been placed here to block vehicular access to this part of the street and is close to two similar posts - although neither of those carry inscriptions - J3272 : Old post, Belfast & J3272 : Old post, Belfast.
