Welcome to the site Napoliforme

Amidst the reeds on the shore of Lake Avernus, in a romantic and mysterious landscape, stands the Temple of Apollo: a large octagonal hall, covered by a monumental dome, which according to legend is linked to the cult of the dead - Lake Avernus is the entrance to the underworld - and to the Cumaean Sibyl, oracle of the god Apollo and link between the living and the dead. Like the other "trugli" in the area (from the Latin trulleus, the name used from the 15th century onwards by scholars to indicate circular structures covered by domes, considered temples), it is actually a thermal hall, the frigidarium of a complex that extends along the entire slope of the Avernus crater to the shores of the lake, where, as in nearby Baia, the Roman aristocracy built villas and baths that exploited the curative waters of the Phlegraean. The exterior plan of the hall (1st century AD, renovated in the 2nd century AD) is octagonal, while the interior plan is circular, with a diameter of 37 metres, and articulated on two levels, lit by arched windows.
