The first comprehensive geological map of London and its environs was published in 1856 by Robert William Mylne. He was part of a celebrated dynasty of Scottish architects, water engineers and surveyors, and the son of William Chadwell Mylne, who was ‘Engineer to the New River Company’ which supplied London with “fresh drinking water” from the River Lee in east London.
Mylne himself had created a large practice as a consulting water engineer, and in 1856 published his ‘Map of the geology and contours of London and its Environs’ at a scale of 4 miles to the inch. This was followed by a smaller version entitled ‘Geological map of London and its Environs’ at a scale of 1:45,000.
This was an important map in its day: it was first published in 1856 in a period of great change in the understanding of public health and disease in cities, and the need for major public works such as improved water supply and sewerage systems. A detailed geological map was essential to this work.
This 1871 edition of the map has now been reproduced by the BGS, at its original size, as a faithful facsimile of an original held in the Survey’s library. It gives a glimpse into the fascinating history of urban development in London in the mid 19th Century – a wonderful map for any London historian.
