Beneath naples runs an underground geothermal zone called the campi flegrei ( fiery fields ) .

在那不勒斯下面有一片被称为“炙热地域”的地热带。

Maybe more interestingly , you can also find places of worship , cult burial chambers , and ancient tunnels buried in the volcanic sandstone making up the campi flegrei .

更有趣的是，你能在那里找到古人祭祀的地方、异教徒的墓室和掩埋在火山岩中的古老隧道。
