There are several things to see and do in Pyrgos, but these should be at the top of your list:
Walking around Pyrgos is tantamount to exploring an open-air museum. Thanks to its “protected settlement” status, a big part of the entire settlement is preserved to be entirely authentic.
Enter through the Kastelli Door (“Kastelloporta”) and feel the looming sensation of the weight of the structure, as well as the artistic poetry of its archways and pathways. Keep going up its sloping, meandering ways and be rewarded by the breathtaking, gorgeous view of the entire island and the Aegean.
There are a whopping 48 churches in Pyrgos alone, and some of them are the oldest ones in Santorini. Most of them, however, can only be enjoyed from the outside as they are privately owned.
This monastery dedicated to the Prophet Elias was built in the early 1700s and is also quite fortified. It also boasts a gorgeous church at the highest point, as is tradition for churches dedicated to the Prophet Elias.
