In 1868 Lydham was described as a parish partly in the hundred and county of Montgomery, but chiefly in the hundred of Purslow, 2 miles N.E. of Bishop's Castle, its post town, and 8 S.W. of Church Stretton. The main road from Bishop's Castle to Shrewsbury passes through the village. The small river Camlet rises in the parish, which includes the township of Aston. A portion of the people are Welsh. The church is an ancient stone edifice, dedicated to the Holy Trinity.
