Tilbury and Southend Railway and its terminus at Fenchurch Street railway station, and thus this valley can no longer be seen in the modern contours. Bentley then goes on to provide detailed evidence for the Lorteburn's existence. Archaeological evidence has identified dried stream beds in this part of the city. Discoveries include: Mariner House, Crutched Friars (Peter Marsden 1963-4) a small stream in the natural gravels, on an east to west alignment. 2-4 Jewry Street (Peter Rowsome 1980) a stream in a section cutting through the natural brickearth, on a north to south alignment. Rangoon Street (David Bowler 1982) two stream-beds were observed following differing courses. Bentley interprets this evidence as a stream called the Lorteburn recorded east of Seething Lane in the late 13th century. Early references Bentley has identified that: A very different course is described in 1603 by John Stow, giving the name as 'Langborne' and describing the route as running along Fenchurch Street, Lombard Street, and Sherbourn Lane. Stow states that the river gave its name to the Langbourn ward of the City of London. The stream was either covered over or dry by his time. In 1770 John Noorthouck gives a similar description to Stow, with some additional details. The church of St Katherine Coleman is indeed at the head of the course of the Lorteburn described by Bentley, but the rest of Stow and Noorthuck's descriptions are problematic given that they would require the water to flow uphill in the vicinity of Mincing Lane (see below). Nicholas Barton's disbelief The 1962 book Lost Rivers of London by Nicholas Barton is considered by many to be the foundational work on London rivers. Barton refutes the existence of the Langbourne for three reasons: "It does not fit in with the contours, and actually involves the proposed stream's flowing uphill to the extent of three feet, both in the ancient and modern ground levels." "During the construction of the Gracechurch Street sewer the builders specifically looked for it and found no traces." "Stow more or less admits that he himself has nothing more to go on than the name." Barton's denial of the stream thus rests on Stowe's description, which describes a route far to the west of the one proposed by Bentley. Inclusion on modern maps The Lorteburn is included on some modern maps of Roman Londinium and early Medieval London. The above map is reproduced
