Argyroupoli is a small town in the province of Rethymno, built in a beautiful location at an altitude of 260 meters above the valley of the river Mouselas. The settlement has been characterized as traditional, as it preserves many of the architectural elements of the rich past.
Argyroupoli is built on the site of the ancient city Lappa. Scattered monuments from the Roman, Byzantine, and Venetian periods indicate the strategic importance of the city that flourished in the depths of the centuries.
It is worth walking in the narrow alleys of the village, to see the traces of the mosaic floors, the Byzantine frescoed churches, and the Venetian mansions. You can also visit the nearby necropolis of ancient Lappa with the carved Greco-Roman tombs, the monumental plane tree, and the temple of Pente Parthenes.
However, the place that accepts the most visitors is the famous Springs of Argyroupoli, which are formed in a green setting a few meters below the village. The water comes out of the cave of Agia Dynami and after passing the old watermills that once ground the grain, they end up in the riverbed of the river Mouselas. The watermills today have been turned into taverns that offer traditional food.
Kalonyktis Tower (Koules) 
The koule of Kalonyktis is located on the hill of Agiasmatsi on the outskirts of the village of Kalonyktis in the province of Rethymno. This large tower was built by the Ottomans after the Great Cretan Revolution of 1866, being part of the large network of towers - koules - for the control of the Cretan revolutionaries.
