The Cathedral of San Pardo preserves the remains of the saint, patron saint of the city, and has a Gothic-style facade, in rough stone, and a beautiful wooden portal with a lunette and pointed arch, a characteristic and visible thirteen-ray rose window enclosed in a frame at the base of which there are two lions. 
The interior, very bright in Gothic style except for the modern roof of the main nave, is divided into three naves, of different sizes. 
The marble altar can be traced back to the 18th century, while the works belong to Solimena, Giordano and de Ribera. Finally, the bell tower, built-in 1451, has a very particular clock and five bells inserted inside the octagonal building.
