Postmen have been told they are no longer allowed to collect letter from a post box after it was deemed a safety risk having been enveloped by a tree. The Royal Mail has boarded up the Grade II listed post box, saying that after 120 years of service in Cardiff, it was no longer safe for its staff to collect letters from it. A bi-lingual sign on the red box, which dates back to 1891 bears Queen Victoria’s initials, reads: “Regrettably Royal Mail has had to remove this posting box from service as, due to the growth of the tree and the raised pavement, it is no longer safe to collect mail from.”There are alternative posting boxes a short distance away,” before listing the nearby replacements in the wealthy suburb of Roath.But residents have branded the move “health and safety madness”, pointing out that the well-used postal box has survived two World Wars, but has now been decommissioned due to “postmen worried about stepping over a root or two”. Houses on the street were built on land owned by the Bute Family who brought power and prosperity to the Welsh capital by developing the city’s docklands for the coal trade.Building work began on the road in 1891 and was finally completed in 1910. The London Plane was planted as a sapling but now stand towering more than 120ft.Meg Bryant, 32, said: “This postbox has survived two World Wars and millions of letters – but why are the postmen worried about stepping over a root or two.”Surely it can’t be too much of a risk to step over the tree roots. It is a lot less dangerous that a barking dog coming at a letterbox.”Conservation policies dictate the oldest and rarest letter boxes must be protected within their community.Father David Leyshon, 46, said: “It is a real landmark and a talking point – it is a shame it is now being blocked up by the Royal Mail.”They should make a feature of it rather than consign it to the rubbish bin of health and safety madness.” The sign on the now-blocked off post boxCredit:Wales News Service Local councillor Sue Lent said: “The postbox has always been there and the tree wasn’t always so far around it. It wasn’t like that years ago. The postbox was certainly well used in the past.” A baffled resident at the blocked post box in CardiffCredit:Wales News Service The box is on historic Ninian Road in the Welsh capital – named after Lord Ninian Creighton-Stuart, the former MP for Cardiff, who was the son of landowner the 3rd Marquis of Bute.
