There is a large benchmark Image on the stone at the left foreground of the image

Ordnance Survey records indicate that the Carlisle 1, Penrith 17 milestone was located here and had a benchmark levelled at 88.782 feet above Liverpool Datum cut on its top during the 1841-1844 Liverpool to Port Carlisle 1GL Survey. The surveyor's description was 'No. 467. Mark on top of the 17th milestone from Penrith ; 2.13 ft. above surface'

A cast iron post once used to mark the location of underground telephone cables. For more detail, see Image . Located on London Road (A6) below Summer Hill. The junction with Trevor Street can be seen at end of this wall - there is an identical post there http://www.geograph.org.uk/photo/5222637 . Two more examples spotted on London Road at Harraby http://www.geograph.org.uk/photo/5222640 & http://www.geograph.org.uk/photo/5222642 .

For location, see Image . At the top of the cast iron post is a crown and the initials ER - pretty sure this dates it to the reign of Edward VII (1901-1910). Originally there would have been numbers attached showing the distance in feet and inches to a buried telephone cable or junction. The arrow symbol was an official identifier of government property. At the time this was installed much of the telephone network in the UK, including all trunk lines, was run by the General Post Office http://www.britishtelephones.com/histuk.htm . Later cable markers (made of concrete) had 'GPO' stamped upon them - see Image .

Ordnance Survey pivot benchmark not mentioned in OS records

A rusty cast iron post from the Edwardian era, located near the junction of London Road (A6) and Trevor Street. Used to mark the location of underground telephone cables or joints. For more detail, see photo of an identical post about 35m along the street Image Two more of these markers can be seen further out of town, on London Road at Harraby http://www.geograph.org.uk/photo/5222640 & http://www.geograph.org.uk/photo/5222642. UPDATE : This marker post has now been removed. It was present in Google Street View images in March 2019, but by September 2020 the post had gone, leaving just a dark mark on the wall behind where it was - see https://goo.gl/maps/TrLBLC9vjnRvEv9s9 .

There are two benchmarks Image on the coping stones of the stone wall at the left hand side of the image
