The facade had been subjected to two interventions; one in 1469 and the other in 1913. The family Racola de Fontanellis, whose coat of arms appears on a decorative element on top of the polifora, commissioned the first intervention.

The fresco paintings were also executed during this period and belong to Dario da Treviso, whose signature is inscribed under the balcony together with the inscription: “1469/ DESIDERIUM IMPIORUM PERIBIT/ DARIUS P.”

In 1913, the former owner eng. Francesco Trojer intervened on the part of the palazzo corresponding to the south spans, integrating the intonaco and the stones elements according to the original decoration and adding his own coat of arms.

The restoration of the façade of Palazzo Trojer began under the direction of the Superintendency of Monuments, Fine Arts and Environmental Heritage of the region Veneto, with financing of Pianca S.p.a. and in collaboration with:

Malta Centre for Restoration – Malta
Hochschule für Bildende Künste – Dresden – Germany
Istituto Veneto per i Beni Culturali – Venezia

Chemical and physical testing was conducted to determine conservation problems and causes of decay and the biological growth was identified. During the cleaning phase large areas of polichromy came to the surface.

Analyses revealed the composition of the various carbon deposits on stones, frescoes and plaster, the composition of the traces of gold gilding remaining on the capitals as well as the presence of stone polychromy
