It is a church with a Latin cross floor plan, with an interior featuring a 15th century cloister with two Baroque doors, the altar and the 45 metre high blue dome.  Under the dome is the Communion Chapel, considered one of the most beautiful examples of Spanish Baroque architecture. Very close to the Co-cathedral of San Nicolás you will find Alicante’s Town Hall and the picturesque neighbourhoods of Santa Cruz and San Roque. Translated with DeepL.com (free version)
