Marple Aqueduct is a Grade-I Listed structure and Scheduled Ancient Monument on the Peak Forest Canal in Greater Manchester. The aqueduct was constructed in 1800 and carries the Peak Forest Canal over the River Goyt.
The structure consists of three semi-circular masonry arches, supported on stone columns. It is a total of 112m in length and 27m off the ground. As with most aqueducts in the UK, no parapet was provided on the offside, resulting in an unprotected drop of 30m. The brief was to install a parapet that should be an understated visual enhancement, without detracting from the heritage structure.
