Torre di Coltellazzo, Nora,Pula (CA)
Known also as“Coltellaccio” tower, or “Coltellas”, but moreover as “Coltellazzo” or “Castellas”, the Tower of Sant’Efisio stands about thirty five meters above sea level , on a promontory overlooking the bay of Nora , near the ruins of the Punic- Roman. After 1574 , it became necessary to build defense towers and lookout on all coastal areas of the Mediterraneo ruled by Spanish (including Sardinia), to face the growth of pirates invasion from North Africa.
Built in the late sixteenth century to ensure the defense and control of the Gulf of Cagliari in collaboration with the towers of Cala d'Ostia and San Macario , the tower of Saint Efisio seems to have been built on the ruins of previous buildings, perhaps some roman castles, using materials from moles of Nora. It became operative in the early seventeenth century , the tower acquired the name of " Sant'Efisio " in the second half of the same century.
he structure had a cone section shape with a small vertical parapet. The entrance is open to about 6 meters above the ground and facing south , opened into an inner chamber , 7.5 meters wide and with a domed ceiling , central pillar and stiffened ribs. Here there were derived some quarters , including the room of the alcalde (military commander), the accommodation of the soldiers ( at least six ), the powder magazine , storehouses, the galley and the kitchen. It was entered in the top of the tower through a rope ladder .
To raise the alarm, at night they used to light fires in a large iron basin placed on top of the tower. By day, it could use smoke derived from the combustion of bitumen and wet heather.
On top of the tower it was placed a cannon, by which they tried to bomb enemy ships .
Between 1722 and 1728 the tower was changed in a fort by the engineers Antonio Felice De Vincenti, with the help of engineer Bellin and captain Audibert. From the XIX century it suffered arbitrary changing which altered its shape and function, like, for example, the insertion of a external stair in order to facilitate climbing to the entrance.
Now you can climb until the basement of the tower through a pathway behind the archaeological area. You can’t explore this structure without a permission by the superintendence.
The tower garrison gave security against assaults from the sea to the internal territory where, meanwhile, Nora’s people had retired (building the new village of Pula). The business activity of the tower ended in the 1842, when was cancelled the establishment of the Tower Administration in Sardinia.
Afterwards the tower of Coltellazzo began the Pula semaphore station .
Now it houses the lighthouse property of the Navy, and it provides useful information to Mariners
