The 10th century AD venetian Castle of Platamonas, one of the most significant tourist destinations in Pieria prefecture, is a fortress-town of the middle Byzantine period at the southeastern foot of Mt. Olympus, nestled on a hill beside the sea in a strategic position above the shortest route between Macedonia and Thessaly.
The Castle, a walled medieval settlement, is one of the most beautiful and best preserved castles in Greece and, given its position, controlled the road to the entrance of the Valley of Tempe, the strategic passage to southern Greece.

Built on the site of the ancient city of Herakleia, named after the demi-god Heracles (Hercules), Platamon (Platamonas) Castle recently underwent restoration work and is now not only fully accessible to visitors, but also hosts concerts and other cultural events during the summer.

An imposing site by day, the Castle takes on a breathtaking charm at night when the newly-installed floodlights are turned on.
