Designed by Juan Barceló. The temple is formed by three naves with four segments and side chapels. Particularly standing out are the vaults with a transept dome covered by blue stained-glass. Direct light enters through eight splendid large windows. On the inside of the temple are valuable works of art like The Saviour by Josep Ferrer and The Passages in the Life of St. Bartholomew by Morella native Joaquin Oliet on the dome. A 17th century painting by José Orient on the 1397 Barbary pirate attack is currently being conserved there.
