Giovanni Capula

Giovanni Capula was an architect of likely Sardinian origin of the 13th–14th century.

Little is known about him, the inscriptions of the Tower of San Pancrazio and the Tower of the Elephant of Cagliari, where he's defined Architector optimus, are the only direct sources available.

For Dionigi Scano it was of Sardinian origin, being his surname (Capula) often found "in the toponymy and topography" of Sardinia.

[2] On the other hand, his training as an architect is clearer, which is certainly Tuscan, as evidenced by the style of his works.

Foiso Fois hypothesized that the main tower of the castle of Serravalle in Bosa should also be included in his works.
