Michael Bonnici, in his letter Opera House Project, 1956 (January 30) questions whether the plans for the reconstruction of the Opera House submitted by Sig. Zavellani-Rossi and Alziro Bergonzo are still available for public viewing.
I would like to confirm that these drawings and those of other submissions such as the plans of Sig. Piacentini are preserved among the 15 kilometres of public records held by the National Archives.
