The cathedral was restored between the late 1980s and the early 1990s. In 2001, the St. John's Co-Cathedral Foundation was set up to administer and conserve the cathedral and its museum. The sides of the cathedral were restored between 2008 and 2010, and a complete restoration of the exterior began in July 2014 directed by architect Jean Frendo and eight restorers. Restoration of the central part of the façade was completed in September 2015 and project completion was expected in 2017.
