The suggestive bell tower elevates solitary in the middle of Serra d’Ivrea, where the village of Paerno once was.
In 1250 Ivrea founded the fortified village of Bollengo and ordered the populations from Pessano, Paerno and Bagnolo to establish there. The village of Paerno decayed quickly and only the church and the bell tower remained: the first was demolished in 1731, leaving the second as the only evidence of the past.
The “Ciucarun”, as it is called from the locals, is six floors high, highlighted by five frames made of hanging arches that connect the angular pilasters; from the bottom upwards, it has the typical succession of openings: slots, single and double mullioned windows, all of them walled up except those on the last floor. At the base, on the West side, there is an arch opening visible, now walled up, which was one of the access points to the bell tower, and traces of walls confirm the presence of the connected church.
