In the twenty-eighth year of reign of king Mariano II, in 1293, this inscription commemorates the construction of Saint Philip Tower, after the completion of city's defensive wall and Porta Mari door (which connected Piazza della Maioria or Piazza del Mercato -current Piazza Manno- with the road system outside the city wall).  
The author of the defensive works is Lord Mariano (II), viscount of Bas and "Judge" of Arborea who hopes, according to a medieval formulary, to live happily for a long time and, after death, to rest in Christ.
The text ends with the exhortation for those who go through the tower to pray for him.
