The ancient city of Lyktos or Lyttos (GR: Λύκτος / Λύττος) was one of the most ancient and powerful towns in Crete.
Although the excavations in the area reveal traces of habitation from the Hellenistic years onwards (630 B.C.), the archeologists Georgios Rethemiotakis and Angeliki Lempesi have excavated traces of habitation from the time of the destruction of Lyttos by the Knossians (219 B.C.) in excavated residences of the Hellenistic period.
From the Roman period, the city was subject to new workings as testified by the architectural remnants and the many inscriptions and statues discovered.
Numerous vestiges of ancient structures, objects, and broken marbles are seen, as well as an immense arch of a Roman aqueduct, by which the water was carried across a deep valley by means of a wide marble channel. Traces of the aqueduct which brought its water supply from Kournia, near Krasi village, are still visible today in the rural road to Kastamonitsa village. Lyktos had also a theatre, built in the slope of the hill the design of which we know only from the drawings of Belli (1586).
Finally, the most important discovery is that of a room of nearly 14 metres by 11.40 metres, with marble flooring and a series of four stone platforms along its two longer sides. The room was erected, according to the inscription that was found at the site, at the beginning of the second century B.C. This room was identified as the chamber of the Roman deputies of the city and was very probably destroyed by an earthquake at 365 AD.
Lyktos appears to have still been inhabited in the 7th Century AD as indicated by the excavation of late-roman shops in the area. (Late Roman Empire, 284-610 AD)

Built at 510 m with 319 people Ksidás (GR: Ξυδάς) also known as Lyttos, is located at 3 km from Kastelli in the foothills of the site of the ancient town Lyttos. The first mention of the village goes back to 1368AD, with the name Ksidas.
A burial site was discovered when the road was being constructed, at Chomatolakkos, belonging to late Roman period.
Two gold rings have also been found here, the one with stone, showing the portrait of an emperor holding a spear, and the other with a hoop, showing two interlocking hands. A bronze ring with a Greek inscription, along with golden plates and bronze coins, were also found at this site.

Evangelismos (GR: Ευαγγελισμός) at 360 m above sea level, with 365 inhabitants, lies to the SW of Kasteli, distant only 5 km from the county town and about 35 km from Heraklion.
In earlier years, the village was called Mouktari or Mouchtari and its name figures in a 1381 contract for the buying and selling of grain.
The Byzantine church of the Panagia is worth a visit. On August 6th the village celebrates the feast of the Metamorphosis.
Evangelismos is the seat of the newly (2010) created municipality, according to the National "Kallikratis Project", by uniting the former municipalities of Kastelli, Thrapsano and Akalochori. The name of the new municipality is "Minoa Pediada"
