The Roman aqueduct bridge in Termini Imerese is the largest and best preserved in Sicily. The source was located 5 km east of the city, at the foot of Monte San Calogero where the remains of the two settling tanks can still be seen in the locality of Brucato.
The aqueduct needed to cross the Barratina stream and the earliest the crossing was made at Fontana Superiore with a siphon about 600 m long, of which the well preserved hexagonal compression tower remains, 16 m high and resting on a square plinth of 6 m sides. On five of the sides were windows and from the east side the conduit started. On this tower was once a large inscription, now disappeared: aquae Cornealiae ductus p. XX. The last letters ('twenty feet') perhaps corresponds to the sides of the building.
Later it seems that the aqueduct passed further downstream: in Figurella a double-order bridge of arches is still visible (originally nine in the lower, fifteen in the upper: two arches for each order collapsed), 14 m high. The structure with facing blocks is the same as that of the amphitheatre and the curia and shows that it belongs to the same building project of the Augustan colony.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
