This is a town whose size is amongst the most compact of the valley, although in the Middle Ages, it was the political and economic centre of the middle and lower valley. Terzo and its ‘borgo’ (small suburb) boasted a wealth of activity and commercial traffic thanks to an economy based on iron-working and grain-milling.
It was the rule of the Terzi family that was the decisive factor in the development of Terzo and its suburb, Borgo, and it was this same family that founded Castle Terzo (which no longer survives).
However, there are still a few important buildings remaining that give us an idea of the history of this village, set in the heart of the Val Cavallina: there is the convent and church of San Pietro in Aria; the convent and church of San Michele; Palazzo Terzi; the Borgo or suburb (with its remaining millstones, forges and hammers); the Torrazzo, the courtyards of the notaries’ chambers; the church of Santa Maria Assunta, with the Oratorio dei Disciplini (both recently restored).
The municipal district of Borgo di Terzo is the current seat of the Unione dei Comuni della Media Val Cavallina (Union of municipal districts of the middle Val Cavallina).
