In the 16th century, the antiquarian John Leland described the bridge in one of his Itineraries: "From Monk's Gate the wall extends Westwards to the river Monnow. In the wall are four gates: Monk's Gate, East Gate and Wye Gate ... and Monnow Gate which is above the bridge crossing the river Monnow."[41] A visual depiction of the bridge and gate is included in John Speed's work The Theatre of the Empire of Great Britain, published in 1611. His map of Monmouthshire includes an inset map of the town that shows the Monnow Bridge and Gate as well as a similar gatehouse on the Wye Bridge.[lower-alpha 6][43]
