Basically cathedrals are large and fancy Christian churches
Coinciding with this development, we find the earliest "complete" property census in Sicilian history, undertaken primarily to facilitate taxation of assets. These (for they "revealed" assets) listed smallholdings as well as larger (feudal) ones. Not only could the crown levy taxes, but until 1812 (with the abolition of feudalism) the nobles and other feudatories (including the church) could still impose certain minor taxes upon the residents of their territories. The sad fact that medieval terms such as and (from the French for "serf") appeared in Sicilian records into the eighteenth century, while the names of the wealthy were preceded in civil and ecclesiastical documents by titles such as indicates that the road to equality was indeed a long one.

Arab society had its peculiarities for those who were not Muslim. Christians and Jews were taxed more heavily than Muslims, and there were restrictions on the number of new churches and synagogues that could be built (Palermo's cathedral and some other churches were converted to mosques). Church bells could not be rung, and Christians could not read aloud from the Bible within earshot of Muslims or display large crosses in public. Christians and Jews could not drink wine in public, though Muslims sometimes did so in private (something the noticed in the during the eleventh century). Jews and Christians had to stand when Muslims entered a room and make way for them in the souks, streets and other public places. In Arab Sicily there was harmony if not absolute tolerance.
Hailes Church was built in 1130. On the walls are the remains of murals dating from 1300, and a fine St. Cecilia on the Chancel window jamb, dating from 1290. The rood screen is medieval, and the pulpit is Jacobean. This is one of the original 3-decker pulpits, where the Rector would have gone up to the top deck to preach, so that he could look over the sides of the box pews and see his congregation. The Commonwealth arrangement in the Chancel is still retained, with the oak-panelled seats and the Puritanized style of altar, as the seventeenth century table stands on the original altar stones. The Church is located next to Hailes Abbey.
