St John’s Co-Cathedral

St John’s Co-Cathedral is a Roman Catholic church located on St John’s Street in Valletta. The building is known for its great historical, cultural, and architectural significance, embodying centuries of Maltese heritage. Built between 1572 and 1577 by the Knights of Malta, the church is considered to be one of the finest examples of high Baroque architecture in all of Europe.

Refurbishment is required on the church’s existing exhibition areas as well as on the historical façade along the building’s perimeter. The project will also see the construction of a new exhibition hall within the vicinity of the Cathedral’s Oratory and Bartolott Crypt. Due to the grandness of the church and the workload required to reconstruct it, AX Construction has been put in charge of coordinating an extensive team of engineers, restorers, archaeologists, stone masons, and highly specialised construction professionals who are all contributing to returning St John’s Co-Cathedral to its full glory.

This project requires works such as structural alterations on existing walls and ceilings, excavation with the intent of deepening the existing basement, installation of waterproofing, drainage, and runoff systems below and above ground, installation of thermal insulation, restoration of external street façades, internal courtyard façades, internal spaces, and internal and external apertures, and fabrication of various structural steelwork items. Moreover, construction works are being done on foundations including pads, strips, rafts and piles, HCB retaining walls, service shafts, perimeter ground drainage, and ground slabs, a new reinforced concrete Tapestry Hall, reinforced concrete walls, columns, suspended slabs, and flat roofs, a soft stone external façade of the Tapestry Hall, and reinforced concrete stairwells along with a concrete finished spiral staircase.
