Melin Llandegfan was probably built in the 1820s and it is recorded on Dawson's map of 1831. It is named "Twr-y-Felin" on the 3 editions of the 25-inch O.S. maps. It ceased working before the First World War and is marked as "old windmill" on the OS 1" map of 1918. According to Rex Wailes the cap and remains of the sails were still in position in 1929, but they had disappeared, and the top of the tower reduced from five storeys to four, by 1937. Shortly after the local Water Authority installed a large water tank in the tower to provide water for the village, but it was removed in 1989. The ivy-grown tapered rubblestone tower is in a private garden and its interior is inaccessible.
