The Old University Building ( or "L-Università l-Antika"), also known as the Valletta Campus, is the original campus of the University of Malta, located adjacent to the Church of the Jesuits in Valletta, Malta. Construction of the building began in 1595, and it originally housed a Jesuit college known as the "Collegium Melitense Societatis Jesu". The building had to be repaired after being damaged in an explosion in 1634 and an earthquake in 1693.
