The Mezzà: the façade with the sun-dial. The ground floor was occupied by offices,
 the rest by private housing of the workers. The sun-dial, as can be read in an essay by
 the architect Alberto Alpago Novello, with annotations by Mario Gregorj in Domus
 - December 1930 - is from the early 1800's and is a work of an artist who worked
 in the province of Treviso.
