This cache leads you to the cavernous temple of Agia Dynami (Holy Force) that is located in Argyroupoli. Within this small chapel there is a huge spring 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. The water which flows into the chapel is said to be miraculous. Lush green and many small waterfalls dominate in the area. These sources once powered mills for grinding grain. The springs are one of the most attractive places in Argyroupoli (previously known as Lappa). Don’t miss it out to take your lunch or dinner in one of the taverns under the shadow of ancient plane trees.
