The Campanile or Bell Tower (Welsh: Y Tŵr Clychau) is a prominent structure in the village of Portmeirion, in Gwynedd, northwest Wales.

It used stone from a 12th-century castle, the remains which lay a short distance to the west of the village (and which had been demolished circa 1869).

[2] A plaque at the base of the tower ironically reads "This tower, built by Clough Williams-Ellis, architect and publican, embodies stones from the 12th century castle of his ancestor Gruffydd ap Cynan, King of North Wales ...It was finally razed c. 1869 by Sir William Fothergill Cook, inventor of the Electric Telegraph, 'lest the ruins should become known and attract visitors to the place.

'"[4] At seven-storeys in height, Williams-Ellis planned the tower to be the most prominent building and focal point for his new village.

At the apex of the copper roof is a golden ball and, on top of that, a weather vane.
