La Spezia Cathedral (Italian: Duomo della Spezia; Cattedrale di Cristo Re; "Cathedral of Christ King") is a Roman Catholic cathedral in La Spezia, Italy. It is the cathedral of the Diocese of La Spezia-Sarzana-Brugnato. It was built between 1956 and 1975 to designs by Adalberto Libera.
La Spezia became an episcopal seat in 1927, when Pope Pius XI created the new Diocese of La Spezia-Sarzana-Brugnato. The ancient church of the Abbey of Santa Maria Assunta was elevated to the status of pro-cathedral for the new diocese on 19 March 1929, but the project of the construction of a new cathedral was immediately set in motion. The chosen site was on a hilltop cleared at that time in order to link the historic districts in the centre of the town with those to the east, where previously had stood a Capuchin friary.
A competition was announced, in which the winning entry was that of the architect , but the works were postponed by more than 25 years until the mid-1950s, and Del Giudice's designs were never implemented.
In the revived project of 1956, the Rationalist architect Adalberto Libera was chosen, who availed himself of the potential of the elevated site on the vast Piazza Europa to emphasise the monumentality of the religious building.
On the death of Libera in 1963, the building was still unfinished and its completion was entrusted to the local architect Cesare Galeazzi who resumed construction, incorporating some variations of his own. In 1975 the works were completed and the cathedral was consecrated and dedicated to Christ King of the Ages (Cristo Re dei Secoli).
The exterior of the imposing structure is strongly characterised by its circular plan and by the external wall, in the shape of a hyperboloid of one sheet, without any openings. The large churchyard, in part a garden, faces uphill and onto it open three entrance portals.
The interior receives light from the opening in the centre of the vast cupola, with a diameter of 50 metres, supported by 12 massive columns symbolising the Apostles. A second source of light comes from a band of stained glass windows running around the perimeter of the main space. The pavement of white and grey marble, slightly sloping, converges towards the central altar of white marble, while the presbytery, paved in red marble, is slightly raised.
