The great nave ceiling at St David's cathedral is one of the greatest timber works of art in Wales. The ceiling is dominated by huge pendants which float impressively above the name but are without any religious symbolism whatsoever.
The roof has been the object of much admiration since the late sixteenth century but it is not known exactly when it was built or indeed who built it. Various myths have collected around the roof: it is said to have been made of Irish bog oak and by Flemish (or 'foreign') craftsmen. The roof has a strongly marked Renaissance character, especially in the detailing of the pendants. It has twelve bays (with obvious symbolism) and pendants at the intersections of the moulded beams. The pendants are in the form of little castles with carvings of renaissance type of masks and paired dolphins.
