Walking the Circle Line: Tower Hill to Blackfriars
I’ve been walking London Underground’s 14-mile long Circle Line, trying to stay as directly above the line as I can manage. Along the way I’ve been taking large format photographs with a primitive pinhole camera. This installment leads me from Tower Hill to BlackFriars.

From Tower Hill, the Circle Line slowly makes its way to the River Thames. First stop Monument.

The Monument marks the most destructive event in London’s history. In 1666 a fire started in a bakery on Pudding Lane and over the next three nights it would destroy more than 80% of London. Wren’s Monument, at 202 feet high, stands 202 feet from where that bakery once stood. While the city was destroyed, few lives were lost and it stopped the Great Plague in its tracks.
On to Cannon Street, opposite the station in a small alcove is perhaps the strangest and probably the most ancient relic in all London. Yet few people, even Londoners, know it is there. The London Stone could date from as far back as 1100BC, and at latest 200AD. The most likely explanation is it stood as a roman marker of the centre of the city.
Through history, it has been the place where laws were passed, traitors hanged, and revolutions launched. You can find references to the Stone in the writings of Shakespeare, Dickens, Wren, and Blake, so it seems a little sad that now looks like this - trapped behind what looks like a tatty old fireplace. The stone itself is hidden behind some glass or perspex. Passers-by were far more intrigued why I was taking a photo of it than what the object actually was.
From Cannon House, the line passes Mansion House and takes aim at Blackfriars. Halfway way down the hill I venture a hundred yards north for the obligatory photograph of the dome of St Paul’s.

And then a hundred yards south of the line on the shore of the Thames, Millennium bridge crossing over to the Tate Modern.

Finally, just outside BlackFriars tube stop is Blackfriars Railway Bridge, this photograph is of the remains of an earlier railway bridge, dismantled as it could not take the strains of modern trains.
