The small temple of Agios Nikolaos from the 14^th century is only preserved today from the important Zaros monastery.

The church is 900 meters from the southern entrance of the Agios Nikolaos gorge, in Zaros, of the Festos municipality. It is a monastery of Greek Old Calendarists today.

It appears to have been a woman monastery that was desolated after some destruction.

It was a monastery dependency of the Varsamoneri monastery during the Venetian Occupation and it was called Agios Nikolaos in Karopouliana. It was a livestock monastery dependency.

The monastery dependency was preserved during the Turkish occupation. Then, it was desolated and was inhabited again in the 19^th century. In the 19^th century its radical renovation took place keeping only the Agios Nikolaos temple unchangeable.

According to tradition, in the ancient years the temple of Poseidon is said to have been in the area of Agios Nikolaos, in the place of which the Christian temple of Agios Nikolaos was built.

The small cavernous skete of Agios Efthimios is in the eastern side of the gorge, 500 meters from the Agios Nikolaos Monastery.

According to the tradition, the nuns of Agios Antonios monastery killed hermit Efthimios when they saw him in the gardens of the monastery wearing an animal fleece.
