Segorbe cathedral is the most emblematic building in the diocese. It was built backing on to the medieval wall and joined by an arch to the bishop's palace. The main 17th century facade rises from the feet of the temple, with a first body of matching pairs of Tuscan columns and split pediment crest and attic. Beside this is the bell tower, built of ashlar stone from the fourteenth to the sixteenth centuries, with a trapezoidal floor plan and three storeys, with the set of bells in the last section and shrine-like construction on the terrace for the hour bell.

The interior of the cathedral temple stems from the neo-classical renovation done to the plans of academic architect Vicente Gascó from 1791 to 1795, to replace the old 14th century gothic structure. This is a building with a large single nave, semi-circular headwall and chapels between buttresses, with an arrangement of matching pairs of compound pilasters and barrel vault, with a choir at the foot screened off with a 15th century grille and chairs made of carved wood by Nicolás Camarón (1725-1726), lost to a large extent in 1936. The temple contains mural pictorial decoration by José Vergara, in the medallions of the central nave, and by Luis Antonio Planes and Manuel Camarón in the presbytery shell.

The cloister With a trapezoidal floor plan through its necessary location between the city wall and the cathedral, the cloister still has seven of the original chapels closed off by 15th and 16th century wrought iron bars. Open to the central garden by pointed arches and upper gallery, it has galleries or lower corridors in sections of gothic ribbing and fashioned supports. One significant part of the construction is the Saviour's chapel, open to the cloister by a beautiful gothic doorway with a baroque door from neighbouring Cartuja de Valldecrist (Valldecrist Charterhouse). This great building project materialised by a tower in the wall was consecrated in 1401 under the protection of bishop Íñigo de Vallterra, covered with an impressive gothic tierceron ribbing, matching the decoration that must have been used at the head of the former cathedral temple, braced with decorated corbels.

The Chapterhouse, started in 1417, with a square floor plan and ribbed vault raised on trumpet arches, has an interesting flooring made of 15th century Valencian tiling.
