The little church at Cascob, in a remote valley on the edge of Radnor Forest, is built in a round churchyard which is a sign that the site is ancient. The oldest parts of the present building are the two 13th century lancet windows on the north side of the nave and chancel. There is a nicely carved screen of 16th century origin. Originally there was a full stone tower but this collapsed and a large pile of debris remains to the rear of the later belfry. Apart from the 14th century font most of the rest is 15th century or later. This church was locked when I visited and there was nobody about to find out where you can get the key, which is a shame because inside there is a curious abracadabra charm made by Sir John Dee, alchemist to queen Elizabeth I, who lived at nearby at Whitton.
