The Monastery of Aghia Irini (Santa Irene) is built at an altitude of 260m at the foot of Mount Vrisinas, about 5km south of Rethymnon. It operates as a nunnery and is one of the oldest monasteries in Crete, built before 1362.

The Monastery of Prophet Elijah (Profitis Elias) is built above a hill with panoramic views, 20km south of Rethymno, next to Roustika village. It is a relatively unknown monastery throughout Crete, although it was founded in the Venetian Era and belongs to the most historic convents on the island.

Panagia Halevi monastery is located about 6km south of Rethymnon, on the way to Chromonastiri. It's another Venetian monastery of Crete, which is deserted and surely worth restoring.

At the suburb Tria Monastiria of Rethymnon city, just opposite the entrance of the Municipal Cemetery of the city, we meet a ruined stone building with a small church on its roof, in a really beautiful grove.

In the heart of the Old Town of Rethymnon stands the imposing Nerantze Mosque, which today houses the Rethymnon Conservatory. The historic building was originally the main church of the Augustinian Monastery, one of the most important Catholic monasteries established in the city during the Venetian period.

The Monastery of St. Anastasia the Roman, the first in Greece monastery dedicated to Her, was founded in 2008 and started its operation in July 2009. Apart from the main church of St. Anastasia, there is the chapel of St. Kosmas the Aetolian.

The church was recently restored by the Archaeological Service and is now open to the public. The temple was built in the Middle Byzantine period on the site of an earlier basilica of the 3rd AD century, parts of which were later incorporated the church. On the sides four rooms were built, so the final shape of the temple is rectangular.

The cavernous temple of Agia Dynami (Holy Force) is located in Argiroupolis. Within this small chapel there is a huge spring of Holy Force that supplies almost entire Rethymno province with water. Inside the temple there was an impressive mosaic of Christ, which has been now replaced with a simple icon as the initial has been moved to the museum of Rethymnon.
