Fortress of Borgonovo Valtidone
The Borgonuovo oppidum was founded in 1196 by the Municipality of Piacenza to defend the western border of its territories, equipped with a fortress, towers and city walls with an escarpment and fortified entrances. In the current complex, built entirely of bricks, the fortress and the receptacle can clearly be distinguished. These buildings together with the church and the pilgrims' hospital once formed the village of Calendasco. The body of the fortress has typical elements of fourteenth-century Po Valley castles, such as the sawtooth motif combined with the crowning of small windows with segmental arches. The deep moat, the entrance, once equipped with a drawbridge as can be seen from the recesses of the ravelin, and the pusterla, or small door, with drawbridge access are still visible. To the south is a semicircular tower much higher than the rest of the building; the north-east wing, equipped with a scarp and with a rustic appearance and lack of homogeneity, dates back to a later period. The entrance hall, covered by a cross vault decorated with sixteenth-century frescoes, leads into the courtyard where a portico with three arches is visible. The receptacle, a rustic body with small arched windows and a decorative sawtooth motif, is outside the moat, near the bridge-beater.
