The ancient bridge of Eleftherna was built in the first half of the 4th century and is preserved in excellent condition, crossing the torrent Chalopotas. Nearby there was another twin bridge that has not survived. It has a length of 9.5 meters and a width of 5.25 meters. It has a characteristic shape, as there is no arch, but a triangular opening (ekforic architecture).
Near the village of Demati there is a wonderful arched bridge, built by the locals to cross the longest river of Crete, Anapodaris.
Sitia province, because it hosts many springs, hosted several places with watermills. Almost every village hosted one or more mills, unlike most places of Eastern Crete where windmills were used, because of the lack of water. One of the best preserved watermills that is still preserved in a very good condition is the watermill of Chochlakies. Chochlakies is a very small village with a very few residents today at the eastern end of Crete. The watermill of Chochlakies is built on the east end of the village, right on the path that leads to the gorge of Chochlakies and the beach of Karoumes.
Here we meet the imposing Venetian aqueduct of Morosini at position Karydaki, which crosses the river that runs through Sylamos Gorge and ends at Knossos. If you cross the bridge you can visit the ruined church of Panagia Karydakiani monastery, on the opposite site.
The innerland of Crete is full of deserted villages. One of the most impressive deserted villages of Crete, which was quite large, was Kalathiana, located between the villages of Makres and Moroni. Kalathiana was a victim of the general urbanization the prevailed in Crete after the end of the Second World War and was totally deserted at '70s.
East of Limnes village, near Agios Ioannis church, we still meet two of the several windmill parks of Crete. Each park still hosts six windmills in a row (twelve overall), with the roofs being collapsed. These mills are of the more usual mill type, that turns only in a certain wind called Axetrocharis (this has a rectangular shape).
In 1903, the independent Cretan State built a single arched bridge called Kamara that collapsed in 2018. It was 10m wide and very inclined. The place can be accessed by a dirt road that stops here. It was very tough to locate the bridge due to the lush vegetation.
Near the villages of Episkopi and Mourtzana, in a lush green valley, we still see the ruins of the houses and the watermills of the village Mousses or Moussi. In this village we meet the five watermills that took advantage of the abundant water of the area for grinding grain of the surrounding villages. The mills operated till the 1950s, when the modern technology surpassed the traditional way of grinding. Thus, the millers who saw their job diminishing, had to leave this wonderful place and seek their future elsewhere.
