Introduction
The church was extended by the addition of a gabled porch and a low extension built at right angles to the northwest.

The Church of The Holy Cross in Gellilydan, Blaenau-Ffestiniog, is probably a late 18th-century building, formerly a tannery, converted to a Roman Catholic church in the mid twentieth century.
