Hello,
the Nuovo district is located on the opposite side of the river, next to the San Matteo one. It's probably the biggest district, however, not the most populous, as the majority of its surface is covered by the residental area of Giardini Ducali (https://www.planetminecraft.com/project/castelnuovo-and-giardini-ducali/). The other inhabitants of the district are rather rich, but not involved in politics merchants or simple citizens.
Apart from the monuments of Giardini there are many interesting sights worth seeing, such as the San Sepolcro basilica (https://www.planetminecraft.com/project/basilica-di-san-sepolcro-and-the-dominican-convent/), Piazza dei Cavalli, a small fluvia port, the guld's warehouses or the city guard's outpost.
The principal square of the district is Piazza del Popolo, located next to the renaissance Porta del Popolo (the people's gate). Next to the square You can observe interesting houses, such as Palazzo Barbanera, which is the seat of an ancient noble family, most relevant in the area, or the bavarian merchants' house, who are commonly present in the district.
