The cathedral church, dedicated to its founder St Colman, a disciple of St Finbar of Cork, is a plain cruciform building mainly of the 14th century, with an earlier oratory in the churchyard.
Its church of St Nicholas is said to have been built in the 14th century, on the site of a still older edifice dedicated to St Finbar of Cork.
In 1316 the prior of Tywardreath, as lord of the manor, obtained the right to hold a Monday market and two fairs on the feasts of St Finbar and St Lucy, but by the charter of 1690 provision was made for a Saturday market and three fairs, on the 1st of May, 10th of September and Shrove Tuesday, and only these three continue to be held.
It is dedicated to St Fin Barre or Finbar, who founded the original cathedral in the 7th century.
The Roman Catholic cathedral, also dedicated to St Finbar, is conspicuous on the north side of the city; it dates from 1808, but has been since restored.
