Castley is a village and civil parish in the former Harrogate district of North Yorkshire, England.
It lies on a bend in the River Wharfe about 10 miles (16 km) north of the centre of Leeds.
[2] The village appears in the Domesday Book as Castleai, a combination of castel, and lēah, meaning the clearing near the fort.
[3][4] The greater part of the Arthington Viaduct, which carries the Leeds to Harrogate railway line across the Wharfe valley, stands within the parish.
[6] The parish contains the village of Castley and the surrounding countryside, and the listed buildings consist of a house, a boundary stone, a railway viaduct and a milepost.
