The Watchtower stands at the highest point of Collesano, beside today's Mother Church. It is usually dated to the 12th century, although local sources also describe it as medieval or 14th-century in the setting of Piazza Plebiscito.
Originally this was an isolated military lookout protecting an old road route, separate from the first settlement that grew around the castle. As the town expanded and the tower lost its defensive role, it was absorbed into the historic center and used as the bell tower of the Mother Church until the early 20th century.
The structure has a regular square plan on three levels. Access is through a side door; inside, a staircase leads upward to a floor with a valuable high mullioned window and carved capital. Around it, the Piano della Misericordia still preserves a compact layer of civic and religious history.
Built in the second half of the 12th century, originally an isolated military lookout.
Square plan, three storeys, with a 14th-century bifora (two-light window) still visible.
Annexed to the Mother Church when the latter was built; served as its bell tower until the early 1900s.
Stands in Piazza Plebiscito, one of the panoramic balconies over the Madonie valleys.
Timeline
10th–11th c.Arab geographers cite the site as Qal‘at as-sirat, “the fortress of the road”.
c.1140Roger II destroys the older Monte d’Oro stronghold (Qal‘at as-sirat) and moves the settlement down to the present town site — its first nucleus the Bagherino quarter.
12th c.A square watchtower rises here as an isolated lookout over the road below.
14th c.The surviving two-light window (bifora) points to a later building or rebuilding phase.
16th c.The new Mother Church absorbs the tower into its flank and uses it as a bell tower.
until 1912The tower serves as the Mother Church’s campanile.
Stories & traditions
For its first centuries the tower stood alone, a sentinel watching the road while the village grew below around the castle.
A slender two-light window (bifora) with a crocket capital survives on the upper floor — its 14th-century style leaves the tower’s exact phase (Norman, Swabian or Aragonese) unsettled.
The square it crowns, the Piano della Misericordia, is named for a small Church of the Misericordia and looks out between the Madonie peaks and the Tyrrhenian Sea.
